Multiple treatments comparisons

A special method of meta-analysis known as multiple treatments meta-analysis (MTM) is suited to the practical issues addressed by overviews of reviews. However, MTM (also known as ‘network meta-analysis’, or ‘multiple treatments comparisons’ (‘MTC’) meta-analysis) relies on a strong assumption that studies of different comparisons are similar in all ways other than the interventions being compared.

A graphical representation of the individual results of each study included in a meta-analysis together with the combined meta-analysis result. The plot also allows readers to see the heterogeneity among the results of the studies. The results of individual studies are shown as squares centred on each study’s point estimate. A horizontal line runs through … Continue reading The Forest Plot

Fixed- vs Random-effects models in meta-analysis

The selection of a model should be based on the nature of the studies and our goals. The fixed effect model makes sense if (a) there is reason to believe that all the studies are functionally identical, and (b) our goal is to compute the common effect size, which would then be generalized to other … Continue reading Fixed- vs Random-effects models in meta-analysis
