However, the checklist items are applicable to reports of systematic reviews evaluating other non-health-related interventions (for example, social or educational interventions), and many items are applicable to systematic reviews with objectives other than evaluating interventions (such as evaluating aetiology, prevalence, or prognosis). Provide a general interpretation of the results in the context of other evidence. This involves repeating an analysis but using different decisions from those originally made and informally comparing the findings.103 For example, sensitivity analyses might have been done to examine the impact on the meta-analysis of including results from conference abstracts that have never been published in full, including studies where most (but not all) participants were in a particular age range, including studies at high risk of bias, or using a fixed-effect versus random-effects meta-analysis model. For example, authors might consider describing the type of understudied participants who should be enrolled in future studies, the specific interventions that could be compared, suggested outcome measures to use, and ideal study design features to employ. These covariates were included a priori as potential confounders given that programmes tailored to socioeconomic position might include more intervention sessions or components or be delivered by different professionals with varying experience. Alternatively, this could be achieved by, for example, presenting the origin of each data point in footnotes, in a column of the data table, or as a hyperlink to relevant text highlighted in reports (such as using SRDR Data Abstraction Assistant139). Explanation: Users of reviews need to know the risk of bias in the included studies to appropriately interpret the evidence. We anticipated that individual studies would report data for multiple cognitive outcomes. However, standard meta-analysis methods are not appropriate when the effect estimates are correlated. Other materials might include more detailed information about the intervention delivered in the primary studies that are otherwise not available, such as a video of the specific cognitive behavioural therapy supplied by the study investigators to reviewers.73 Similarly, other material might include a list of all citations screened and any decisions about eligibility. If abstracts or articles required translation into another language to determine their eligibility, report how these were translated (for example, by asking a native speaker or by using software programs). If data, analytic code, or other materials will be made available upon request, provide the contact details of the author responsible for sharing the materials and describe the circumstances under which such materials will be shared. Preparing summary of findings tables-binary outcomes, GRADE guidelines: 13. global cognitive function), sub-scales that provide a measure of domain-specific cognitive function or cognitive abilities (such as processing speed, memory), or bothStudies with a minimum follow-up of 6 months were eligible, a time frame chosen to ensure that studies were designed to examine more persistent effects of alcohol consumptionNo restrictions were placed on the number of points at which the outcome was measured, but the length of follow-up and number of measurement points (including a baseline measure of cognition) was considered when interpreting study findings and in deciding which outcomes were similar enough to combine for synthesis. We hope that use of this resource will lead to more transparent, complete, and accurate reporting of systematic reviews, thus facilitating evidence-based decision making.

Meta-regression is an extension of subgroup analysis that allows for the effect of continuous and categorical variables to be investigated.109 Authors might use either type of analysis to explore, for example, whether the intervention effect estimate varied with different participant characteristics (such as mild versus severe disease) or intervention characteristics (such as high versus low dose of a drug).

Many other elements may be present or added. For example, one meta-analysis might include three studies of participants aged 30 years on average, whereas another meta-analysis might include 10 studies of participants aged 60 years on average; in this case, knowing the mean age per synthesis is more meaningful than the overall mean age across all 13 studies. For example, a statement indicating that, unless otherwise specified, all data came from the primary reference for each included study would suffice. Given a sufficient number of trials, we used unadjusted and adjusted mixed-effects meta-regression analyses to assess whether variation among studies in smoking cessation effect size was moderated by tailoring of the intervention for disadvantaged groups. Although nonoperative treatment is often successful in achieving satisfactory outcomes, correct diagnosis and treatment is Correlated effect estimates arise when multiple effect estimates from a single study are calculated using some or all of the same participants and are included in the same meta-analysis. When information regarding any of the above was unclear, we contacted authors of the reports to provide further details.175, Explanation: Defining outcomes in systematic reviews generally involves specifying outcome domains (such as pain, quality of life, adverse events such as nausea) and the time frame of measurement (such as less than six months).37 Included studies may report multiple results that are eligible for inclusion within the review outcome definition.6667 For example, a study may report results for two measures of pain (such as the McGill Pain Questionnaire and the Brief Pain Inventory), at two time points (such as four weeks and eight weeks), all of which are compatible with a review outcome defined as pain <6 months. Multiple results compatible with an outcome domain in a study might also arise when study investigators report results based on multiple analysis populations (such as all participants randomised, all participants receiving a specific amount of treatment), methods for handling missing data (such as multiple imputation, last-observation-carried-forward), or methods for handling confounding (such as adjustment for different covariates).676869. For example, authors might acknowledge the decision to restrict eligibility to studies in English only, search only a small number of databases, have only one reviewer screen records or collect data, or not contact study authors to clarify unclear information. WebThe 2008 Sichuan earthquake (Chinese: ; pinyin: Wnchun d dzhn; lit. Intravenous haloperidol was administered in all except two trials; in those two exceptions, oral doses were given [two studies cited]. We encourage readers to submit evidence that informs any of the recommendations in PRISMA 2020 and any examples that could be added to our bank of examples of good reporting (via the PRISMA statement website http://www.prisma-statement.org/). ORIGINAL ARTICLE. Because sharing of data, analytic code, and other materials is not yet universal in health and medical research,164 even interested authors may not know how to make their materials publicly available. The DEBATEISR study compared a prospective cohort of patients receiving DEB therapy for instent restenosis against a historical cohort of diabetic patients. identify the studies contributing to each subgroup. This is consistent with our findings that teacher training is only effective in improving early grade literacy outcomes when it is combined with teacher coaching. We hope that changes to the content and structure of PRISMA 2020 will facilitate uptake of the guideline and lead to more transparent, complete, and accurate reporting of systematic reviews. If the review is an update or replication of a particular systematic review, indicate this and cite the previous review. Note: the following is an abridged version of an example presented in full in supplementary table S1 on bmj.com. In terms of overall risk of bias, there were concerns about risk of bias for the majority of studies (20/24), with two of these assessed as at high risk of bias (MusherEizenman 2010; Wansink 2013a). The assessments of certainty (or confidence) in the body of evidence (item #22) can support the discussion of such limitations. PRISMA-S: an extension to the PRISMA statement for reporting literature searches in systematic reviews, The search and selection for primary studies in systematic reviews published in dental journals indexed in MEDLINE was not fully reproducible, The impact of the peer review of literature search strategies in support of rapid review reports, Text mining for search term development in systematic reviewing: A discussion of some methods and challenges. For example, in a study that includes children and adolescents, for which the investigators did not specify the age range, authors might assume that the oldest participants would be 18 years, based on what was observed in similar studies included in the review, and should report that assumption. To achieve this, reviewers may opt to publish a protocol in a journal that is open access or provides free access to content (such as Systematic Reviews, BMJ Open) or a journal using the Registered Reports publishing framework (https://cos.io/rr/), where it will benefit from external feedback before publication, or deposit a protocol in a general purpose or institutional open access repository (such as Open Science Framework Registries, Zenodo). We have edited the examples by removing all citations within them (to avoid potential confusion with the citation for each example), and we spelled out abbreviations to aid comprehension. DM is chair of the EQUATOR Network, IB is adjunct director of the French EQUATOR Centre and TCH is co-director of the Australasian EQUATOR Centre, which advocate for the use of reporting guidelines to improve the quality of reporting in research articles. We arbitrarily adopted the I-squared thresholds of >75% to be considered as signs of considerable heterogeneity, but we also judged the evidence for this heterogeneity (through the uncertainty intervals) and the localization on the forest plotAll analyses were run in Stata SE 14.0 (StataCorp, College Station, TX) by one author.183, We based our primary analyses upon consideration of dichotomous process adherence measures (for example, the proportion of patients managed according to evidence-based recommendations). Epidemiology and Reporting Characteristics of Systematic Reviews of Biomedical Research: A Cross-Sectional Study, Psychosocial interventions for supporting women to stop smoking in pregnancy. For an example of individual study results presented for a dichotomous outcome, see figure 2. If any sensitivity analyses were not pre-specified, identify them as such. If non-standard graphs were used, consider reporting the rationale for selecting the chosen graph. This approach may be more reliable than single screening but at the expense of increased reviewer time, given the time needed to resolve discrepancies495051, Priority screening to focus early screening effort on most relevant recordsInstead of screening records in year, title, author or random order, machine learning is used to identify relevant studies earlier in the screening process than would otherwise be the case. The MEDLINE strategy makes use of the Cochrane RCT filter reported in the Cochrane Handbook v5.2. Explanation: Presentation of study results using tabulation and visual display is important for transparency (particularly so for reviews or outcomes within reviews where a meta-analysis has not been undertaken) and facilitates the identification of patterns in the data. technical support for your product directly (links go to external sites): Thank you for your interest in spreading the word about The BMJ. Two review authors independently applied the tool to each included study, and recorded supporting information and justifications for judgements of risk of bias for each domain (low; high; some concerns). Importantly, although we found that bystander programs had a significant beneficial effect on bystander intervention behaviour, we found no evidence that these programs had an effect on participants' sexual assault perpetration. Presenting the key characteristics of each study in a table or figure can facilitate comparison of characteristics across the studies.92 Citing each study enables retrieval of relevant reports if desired. We used cluster-adjusted estimates from cluster randomised controlled trials (c-RCTs) where available. A grade 3 sprain is a complete tear of a ligament, causing instability in the affected joint. If an automation tool was used to assess risk of bias due to missing results, report how the tool was used, how the tool was trained, and details on the tools performance and internal validation. We strive to ensure that every paper is crafted with getting you the highest grade in mind. For a particular outcome and effect measure, this requires specification of thresholds (or ranges) used to interpret the size of effect (such as minimally important difference; ranges for no/trivial, small, moderate, and large effects).91. If authors did not prepare a review protocol, or prepared one but are not willing to make it accessible, this should be stated to prevent users spending time trying to locate the document. The PRISMA 2020 statement: an updated guideline for reporting systematic reviews. Albatross plots are a scatter plot of p-values against the total number of individuals in each study. The register maintains a permanent public record of this information along with any subsequent amendments (date-stamped) and issues a unique number to link the registration entry to completed review publications.153 Publicly recording details of inclusion and exclusion criteria, planned outcomes, and syntheses enables peer reviewers, journal editors, and readers to compare the completed review with what was planned, identify any deviations, and decide whether these may have introduced bias. WebAppendicitis has long been the most common indication for emergency abdominal surgery in children with approximately 12,000 emergency appendicectomies performed in children annually in the UK [1]. Explanation: Discussing how the results of the review relate to other relevant evidence should help readers interpret the findings. 2020. The essential and additional elements are framed in terms of reporting the presence of a method or result (such as reporting if individuals were contacted to identify studies) rather than reporting on their absence. In case of disagreement, consensus on which articles to screen full-text was reached by discussion. Different analytic strategies may be used to examine whether the risks of bias of the studies may influence the study results: (i) restricting the primary analysis to studies judged to be at low risk of bias (sensitivity analysis); (ii) stratifying studies according to risk of bias using subgroup analysis or meta-regression; or (iii) adjusting the result from each study in an attempt to remove the bias. Furthermore, a summary at the level of the synthesis is more usable since it obviates the need for readers to refer to multiple sections of the review in order to interpret results.92. Grade 1. Reproduced from Feng et al.192, The figure displays for each study included in the meta-analysis the summary statistics (mean, standard deviation, and sample size) for the quadruple and triple combination antiretroviral therapies (cART) groups, and the mean difference and its 95% confidence interval for the continuous outcome, CD4 T cell count (cells/L). For the association between corticosteroids and mortality, the OR was 0.69 (95% CI, 0.51-0.93) among 880 patients older than 60 years, the OR was 0.67 (95% CI, 0.48-0.94) among 821 patients aged 60 years or younger (ratio of ORs, 1.02 [95% CI, 0.63-1.65], P=0.94), the OR was 0.66 (95% CI, 0.51-0.84) among 1215 men, and the OR was 0.66 (95% CI, 0.43-0.99) among 488 women (ratio of ORs, 1.07 [95% CI, 0.58-1.98], P=0.84).195. Where multiple results remained, we listed all available outcomes (without results) and asked our content expert to independently rank these based on relevance to the review question, and the validity and reliability of the measures used. We do not capture any email address. Yeh et al. For example, in the United States, the lifetime cost for providing care to a patient 25 years of age with an ASIA Impairment Scale grade A injury is $2.3 million for thoracic injuries, $3. this systematic review and meta-analysis protocol has been published elsewhere [citation for the protocol provided].202. For example, authors might explain that the review was restricted to studies published from 2000 onward because that was the year the device was first available. For example, in the United States, the lifetime cost for providing care to a patient 25 years of age with an ASIA Impairment Scale grade A injury is $2.3 million for thoracic injuries, $3. RC entered data into Review Manager 5 software (Review Manager 2014), double checking this for accuracy. If assessments of risk of bias were done for specific outcomes or results in each study, consider displaying risk of bias judgments on a forest plot, next to the study results, so that the limitations of studies contributing to a particular meta-analysis are evident (see Sterne et al86 for an example forest plot). the method used (such as Mantel-Haenszel, inverse-variance).103. any methods used to identify or quantify statistical heterogeneity (such as visual inspection of results, a formal statistical test for heterogeneity,103 heterogeneity variance (2), inconsistency (such as I2119), and prediction intervals120). Many tools have been developed to assess the risk of bias in studies767879 or bias due to missing results.84 Existing tools typically take the form of composite scales and domain-based tools.7885 Composite scales include multiple items which each have a numeric score attached, from which an overall summary score might be calculated. Additionally, the fact that our (preliminary) moderator analyses found program effects on bystander intervention to be similar for adolescents and college students suggests early implementation of bystander programs (i.e. Sharing of data, analytic code, and other materials relevant to a systematic review includes making various items publicly available, such as the template data collection forms; all data extracted from included studies; a file indicating necessary data conversions; the clean dataset(s) used for all analyses in a format ready for reuse (such as CSV file); metadata (such as complete descriptions of variable names, README files describing each file shared); analytic code used in software with a command-line interface or complete descriptions of the steps used in point-and-click software to run all analyses. Specify the tool(s) (and version) used to assess risk of bias in the included studies. For this situation, a range of methods are available that appropriately model or account for the dependency of the effect estimates. Furthermore, we limited publications to English and Chinese languages. VW is editor in chief of the Campbell Collaboration which produces systematic reviews and co-convenor of the Campbell and Cochrane equity methods group. Sensitivity analyses that removed studies with potential bias showed consistent results with the primary meta-analyses (risk ratio 1.00 for undetectable HIV-1 RNA, 1.00 for virological failure, 0.98 for severe adverse effects, and 1.02 for AIDS defining events; supplement 3E, 3F, 3H, and 3I, respectively). Therefore, it is critical that results are presented for all main outcomes for the main review objective(s) or question(s) regardless of the statistical significance, magnitude, or direction of effect. Readers are referred to Deeks et al103 for further information on how to select a particular meta-analysis model and method. WebFor a Grade 2 sprain, a removable plastic device, such as a walking boot or aircast brace, can provide support. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement was developed to facilitate transparent and complete reporting of systematic reviews and has been updated (to PRISMA 2020) to reflect recent advances in systematic review methodology and terminology. However, for updated and living systematic reviews, there may be some additional considerations that need to be addressed. For example, funders may provide salary to researchers to undertake the review, the services of an information specialist to conduct searches, or access to commercial databases that would otherwise not have been available.

WebThe I-35W Mississippi River bridge (officially known as Bridge 9340) was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Mississippi River one-half mile (875 m) downstream from the Saint Anthony Falls in Minneapolis, Minnesota, United States.The bridge opened in 1967 and was Minnesota's third busiest, carrying 140,000 vehicles daily. Symptoms may include loss of muscle function, sensation, or autonomic function in the parts of the body served by the spinal cord below the level of the injury. A grade 2 sprain is considered a partial tear to the ligament, in which it is stretched to the point that it becomes loose. In a review examining the association between aspirin use and fracture risk, the authors included a table presenting for each included study the citation, study design, country, sample size, setting, mean age, percentage of females, number of years follow-up, exposure details, and outcomes assessed (table 2).191, The table displays for each included study the citation, study design, country, sample size, setting, mean age, percentage of females, number of years follow-up, exposure details and outcomes assessed. Providing a brief summary of the characteristics and risk of bias among studies contributing to each synthesis (meta-analysis or other) should help readers understand the applicability and risk of bias in the synthesised result. Reporting only summary data (such as two of eight studies successfully blinded participants) is inadequate because it fails to inform readers which studies had each particular methodological shortcoming. Random-effects 95% prediction intervals were to be calculated for meta-analyses with at least three studies to aid in their interpretation by quantifying expected treatment effects in a future clinical setting. A review protocol is distinct from a register entry for a review. If the purpose is to evaluate the effects of interventions, use the Population, Intervention, Comparator, Outcome (PICO) framework or one of its variants to state the comparisons that will be made. The Annals of Thoracic Surgery. The American Journal of Medicine - "The Green Journal" - publishes original clinical research of interest to physicians in internal medicine, both in academia and community-based practice.AJM is the official journal of the Alliance for Academic Internal Medicine, a prestigious group comprising internal medicine department chairs at more This could involve algebraic manipulation to convert reported statistics to required statistics (such as converting standard errors to standard deviations),89 transforming effect estimates (such as converting standardised mean differences to odds ratios93), or imputing missing summary data (such as missing standard deviations for continuous outcomes, intra-cluster correlations in cluster randomised trials).949596 Reporting the methods required to prepare the data will allow readers to judge the appropriateness of the methods used and the assumptions made and aid in attempts to replicate the synthesis. If any automation tools were used to collect data, report how the tool was used (such as machine learning models to extract sentences from articles relevant to the PICO characteristics),6162 how the tool was trained, and what internal or external validation was done to understand the risk of incorrect extractions. Report results of all statistical syntheses described in the protocol and all syntheses conducted that were not pre-specified. This explanation and elaboration paper has been designed to assist authors seeking comprehensive guidance on what to include in systematic review reports. The funders had no role in considering the study design or in the collection, analysis, interpretation of data, writing of the report, or decision to submit the article for publication. All authors were involved in revising the article critically for important intellectual content. If the trial did not report the cluster-adjusted estimated or the ICC, we imputed an ICC from a similar study included in the review, adjusting if the nature or size of the clusters was different (e.g. The mission of Urology , the "Gold Journal," is to provide practical, timely, and relevant clinical and scientific information to physicians and researchers practicing the art of urology worldwide; to promote equity and diversity among authors, reviewers, and editors; to provide a platform for discussion of current ideas in urologic education, patient Selective reporting of the results leads to an incomplete representation of the evidence that risks misdirecting decision making and future research. Domain-based tools require users to judge risk of bias within specific domains, and to record the information on which each judgment was based.728687 Specifying the components/domains in the tool used in the review can help readers determine whether the tool focuses on risk of bias only or addresses other quality constructs. (2012) also do not find evidence for statistically significant effects of the onelaptopperchild program. Both single and multiple reviewer assessments can be combined with priority screening5253, Priority screening with the automatic elimination of less relevant recordsOnce the most relevant records have been identified using priority screening, teams may choose to stop screening based on the assumption that the remaining records are unlikely to be relevant. We use standardised language in the explanation and elaboration to indicate whether the reporting recommendations for each item (which we refer to as elements throughout) are essential or additional. If the same set of studies contribute to more than one synthesis, or if the same risk of bias issues are relevant across studies for different syntheses, such a summary need be provided once only. Such statements may be written in the form of objectives (the objectives of the review were to examine the effects of) or as questions (what are the effects of?).31. Search terms were also identified and checked using the PubMed PubReMiner word frequency analysis tool. Acute ankle sprains are commonly seen in both primary care and sports medicine practices as well as emergency departments and can result in significant short-term morbidity, recurrent injuries, and functional instability. MEDLINE(R) In-Process & Other Non-Indexed Citations and Ovid MEDLINE were searched via OvidSP. Explanation: If authors used methods to explore possible causes of variation of results across studies (that is, statistical heterogeneity) such as subgroup analysis or meta-regression (see box 5), they should provide sufficient details so that readers are able to assess the appropriateness of the selected methods and could reproduce the reported results (with access to the data). Describe the processes used to decide which studies were eligible for each synthesis. We assessed risk of bias in the included studies using the revised Cochrane Risk of bias tool for randomised trials (RoB 2.0) (Higgins 2016a), employing the additional guidance for cluster-randomised and cross-over trials (Eldridge 2016; Higgins 2016b).

If any changes were made to the processes used to select results within eligible outcome domains, specify the changes, along with a rationale. Evidence has been reviewed for other respiratory viral infections, mainly seasonal influenza, but no comprehensive review is available of information on SARS-CoV-2 or related betacoronaviruses that have caused epidemics, such as severe acute respiratory syndrome (SARS) or Middle East respiratory syndrome (MERS). In addition to automation, authors increasingly have access to screening decisions that are made by people independent of the author team (such as crowdsourcing) (see box 3). In order to provide a quantitative assessment of the effects associated with reminders without resorting to numerous assumptions or conveying a misleading degree of confidence in the results, we used the median improvement in dichotomous process adherence measures across studiesWith each study represented by a single median outcome, we calculated the median effect size and interquartile range across all included studies for that comparison.184. Darvish was born Farid Yu Darvishsefat () in Habikino, Osaka, to a Japanese mother, Ikuyo, and Iranian father, Farsad Darvishsefat. In this paper, for each item, we explain why reporting of the item is recommended and present bullet points that detail the reporting recommendations. More moderators (study-level variables) can be included in the model, which might account for part of the heterogeneity in the true effects. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium.Because of its high tensile strength and low cost, steel is used in buildings, A second review author checked the plausibility of decisions and the correctness of data. Explanation: Discussing limitations, avoidable or unavoidable, in the review process should help readers understand the trustworthiness of the review findings. When study data are not amenable to meta-analysis of effect estimates, alternative statistical synthesis methods (such as calculating the median effect across studies, combining P values) or structured summaries might be used.28115 Additional guidance for reporting alternative statistical synthesis methods is available (see Synthesis Without Meta-analysis (SWiM) reporting guideline116). If meta-analysis was done, report the summary estimate and confidence/credible interval.
