Workshop A hands-on introduction to NMAstudio: a web-application to produce and visualize network meta-analyses
2023 London
Chaimani, Yu, Metelli
Background: Evaluation of network meta-analysis (NMA) evidence can be challenging and time-consuming, especially when dealing with large networks of interventions. Despite the fact that NMAs are increasingly adopted to inform decision-making, the lack of user-friendly software is still limiting…
Workshop Advanced meta-analysis 1: Random-effects methods to be implemented in RevMan
2023 London
Veroniki, McKenzie, Korevaar, Turner
Background: Meta-analysis is typically used to estimate the mean effect size of an outcome of interest. However, also of interest is estimation of the variability in the effect sizes (heterogeneity), because this allows assessment of the consistency of effects across studies and estimation of the…
Workshop Advanced meta-analysis 2: Performing meta-analysis in the presence of rare events
2023 London
Chaimani, Evrenoglou
Background: Rare events are a common problem in meta-analysis, particularly for secondary and safety outcomes. When the events are rare, standard meta-analytical approaches have important limitations and may lead to biased and imprecise results. Alternative methods have been proposed in the…
Workshop Applying the Instrument to assess the Credibility of Effect Modification Analyses (ICEMAN) in a meta-analysis
2023 London
Schandelmaier, Briel, Varadhan, Schmid, Devasenapathy, Hayward, Gagnier, Borenstein, Van der Heijden, Dahabreh, Sun, Sauerbrei, Walsh, Walsh, Ioannidis, Thabane, Guyatt

Workshop Assessing risk of bias in comparative diagnostic accuracy studies using QUADAS-C
2023 London
Yang, Leeflang
Background: Diagnostic Test Accuracy reviews addressing comparative questions may include studies directly comparing index tests in the same study group. Because these comparative accuracy studies aim to estimate the difference in accuracy between tests (rather than solely the accuracy of each test…
Workshop Assessing risk of bias in non-randomized studies of interventions: introduction to the ROBINS-I tool
2023 London
Sterne, Higgins, Savovic
Background: Non-randomized studies of interventions (NRSI) can provide information about effects of interventions that is not available from randomized trials, but their results may be affected by confounding, selection and information biases. Assessing the risk of bias in NRSIs included in…
Workshop Assessing the certainty of the evidence from network-meta analysis using the GRADE approach
2023 London
Foroutan, Miroshnychenko, Guyatt, Brignardello-Petersen
Background: Assessing the certainty of the evidence is among the Methodological Expectations of Cochrane Intervention Reviews (MECIR) standards, and it is also acknowledged as a key step in non-Cochrane reviews. Appropriate interpretation of the results from network meta-analysis (NMA) requires…
Workshop Better data extraction with Covidence and RevMan Web
2023 London
Mellor, Van Valkenhoef, McLoughlin
Background:
Cochrane review authors can now import completed data extractions and quality assessments (Risk of Bias) from Covidence into RevMan Web. When completed successfully, all the data collected in Covidence are added to the RevMan Web review, and authors are ready to proceed with setting up…
Workshop Cochrane-Wikipedia Initiative: Hands-on workshop to help improve health content that people are accessing online
2023 London
Dawson, Thompson, de Haan
Background: Improving the quality and reliability of online health articles that are accessed regularly across the internet is a significant challenge. Millions of people access medical articles on Wikipedia each day across 286 different languages. On English language Wikipedia alone, 40,000 human…
Workshop Comparing multiple interventions with network meta-analysis
2023 London
Chaimani, Caldwell, Li
Background: Standard meta-analysis methods for clinical trials focus on comparisons of two interventions, such as a drug versus placebo or a new intervention versus standard practice. In clinical practice, there are rarely only two interventions under consideration. Extensions of meta-analysis to…

Houghton, Booth
QMIG Methods workshop:
Background:
As we learned from the COVID-19 pandemic, sometimes questions need to be answered quickly in order to be useful for policy and practice. This applies equally to questions answerable by qualitative evidence synthesis. However, providing evidence quickly may…
