Fixed‐effects meta‐analysis has been criticized because the assumption of homogeneity is often unrealistic and can result in underestimation parameter uncertainty. Random‐effects meta‐regression are therefore typically used to accommodate explained unexplained between‐study variability. However, it not unusual obtain a boundary estimate zero for (residual) standard deviation, resulting fixed‐effects estimates other parameters their errors. To avoid such estimates, we suggest using Bayes...
