Random-effects meta-analyses using the restricted maximum-likelihood method (two-sided tests with no adjustment for multiple comparisons). Primary outcome in bold.

Mod SMD, effect-modifier SMD, which is the change in SMD per one unit change in effect modifier.

^aMeasurement units are years for age and education and standard deviations for distress and mindfulness. The base gender is male.

^bThe random-effects model did not converge, so the fixed-effects model is reported.

^cMultivariate meta-analysis: number of studies contributing to the result/number of studies that measured this outcome.
