Statistical analysis
We combined information from the trials using the general variance–based method,31 which incorporates a fixed effects model and assumes all the variability is due to random error. However, the assumption of homogeneity was rejected when tested using the β2 statistic, implying the presence of significant variation between studies. To estimate and control for this heterogeneity, we applied a random-effects model to estimate the variance component associated with between-study variation.
