Handling Continuous Outcomes in Quantitative Synthesis

WebJul 30, 2024 · Background: Multivariate meta‐analysis (MVMA) jointly synthesizes effects for multiple correlated outcomes. The MVMA model is potentially more difficult and time‐consuming to apply than univariate models, so if its use makes little difference to parameter estimates, it could be argued that it is redundant. Methods: We assessed the … WebJul 25, 2013 · In quantitative synthesis of randomized clinical trials (RCTs) for a comparative effectiveness review, continuous outcomes are usually less straightforward to analyze than binary outcomes.
