|Intervention||Favorable||Unfavorable||Not Statistically Significant||Uncertain Statistical Significance|
Notes: A result is considered statistically significant if p<0.1. The effects reported here are point estimates; the true can lie anywhere within confidence intervals around these estimates, and may well be different from the point estimate. We do not include the confidence intervals because not all studies reported them.
aWe adjusted the p-values for clustering for findings on costs for the GRACE evaluation using a range of estimates of the intracluster correlation (ICC) from the literature. The findings remained statistically significant after the adjustment.
