Meta‐analysis prediction intervals are under reported in sport and exercise medicine
Abstract
Prediction intervals are a useful measure of uncertainty for meta‐analyses that capture the likely effect size of a new (similar) study based on the included studies. In comparison, confidence intervals reflect the uncertainty around the point estimate but provide an incomplete summary of the underlying heterogeneity in the meta‐analysis. This study aimed to estimate (i) the proportion of meta‐analysis studies that report a prediction interval in sports medicine; and (ii) the proportion of studies with a discrepancy between the reported confidence interval and a calculated prediction interval.
