Description:

This Master Prompt would focus on extending conventional pairwise meta-analysis to situations involving three or more competing interventions or treatments. It would guide researchers through network construction, direct and indirect evidence, connectedness, transitivity, consistency/inconsistency assessment, pairwise and network effect estimates, treatment-ranking probabilities and appropriate network visualizations.

A central emphasis would be placed on distinguishing direct evidence, indirect evidence and combined network estimates, while preventing treatment rankings from being interpreted without considering uncertainty and evidence credibility. The uploaded literature explicitly includes network meta-analysis as a method for comparing competing treatments even when direct head-to-head trials are unavailable. It also contains applications combining conventional pairwise synthesis with frequentist network meta-analysis.
