Forrest Plot of studies including data on outcomes of levels of depressive symptomatology. Legend. Two comparisons from RCTs [Ansai and Reblatto (2015) and Moares et al. (2020)] with three treatment arms have been included under the category exercise interventions. The number of participants in the control group in these comparisons has been halved so as to avoid double counting. Black boxes represent the effect estimates (standardised mean difference), and the horizontal bars are for the 95% confidence intervals (CIs). The diamond is for the pooled effect estimate and 95% CI and the dotted vertical line centered on the diamond has been added to assist visual interpretation
