few years ago, we developedmetaan, a package to perform fixed-or random-effects meta-analysis. In terms of random-effects meta-analysis, it of-fered a wide choice of models, including maximum likelihood, profile likelihood, orrestricted maximum-likelihood, in addition to the established DerSimonian–Lairdmethod available inmetanor Cochrane’s RevMan software.

In thisnecessary update, we describe these additions and discuss the new models and theevidence behind them
