Six online databases (PubMed, Embase, Web of Science, Cochrane Central, PsycINFO, and PsycArticle) were comprehensively searched, using recursive searching and grey literature collection strategies. A random-effects model combined effect sizes for different activity outcomes. The Cochrane Risk of Bias tool assessed the quality of the included studies, and sensitivity analysis examined robustness of the results. Twelve studies involving 1916 participants were included. |
