The purpose of this study was to address that gap. Methods. Meta-analysis of randomized controlled exercise intervention trials in adults ≥18 years of age. The primary outcomes were dropouts in the exercise and control groups as well as compliance to the exercise interventions. A random-effects model was used to pool results. Moderator analyses were conducted using mixed-effects ANOVA-like models and metaregression. Statistical significance was set at P ≤ 0.05. Results. Thirty-six studies representing 3,297 participants (1,855 exercise, 1,442 control) were included. Dropout rates in the exercise and control groups averaged 20.9% (95% CI 16.7%-25.9%) and 15.Journal of osteoporosis250423https://www.ebi.ac.uk/biostudies/studies/S-EPMC3686150biostudies-literatureDropouts and compliance in exercise interventions targeting bone mineral density in adults: a meta-analysis of randomized controlled trials.PMC3686150Kelley GAKelley KSfalseDropouts and compliance in exercise interventions targeting bone mineral density in adults: a meta-analysis of randomized controlled trials.Background.
