A simple method to estimate prediction intervals and predictive distributions: Summarizing meta‐analyses beyond means and confidence intervals

A systematic review and meta‐analysis is an important step in evidence synthesis. The current paradigm for meta‐analyses requires a presentation of the means under a random‐effects model; however, a mean with a confidence interval provides an incomplete summary of the underlying heterogeneity in meta‐analysis. Prediction intervals show the range of true effects in future studies and have been advocated to be regularly presented. Most commonly,...
