For network meta-analysis (NMA), the contribution of direct (and indirect) evidence is easily obtained from the diagonal elements of a hat matrix. For NMA, while several methods exist to obtain the contribution of direct (and indirect) evidence of each comparison to its own NMA estimate, it is far less obvious how to define the contribution, or the importance, of each study to any (other) treatment effect estimate. In this paragraph, we show how our definition of importance was motivated by (but is not limited to) the known concepts of direct and indirect evidence proportions in the context of two-stage meta-analysis with inverse variance weights, still based on the common effect model. ./cache/cord-011952-mm06uzxx.txt ./txt/cord-011952-mm06uzxx.txt
