Previous meta-analyses and RCTs reported heterogeneous dropout rates depending on factors such as geographic location, sociodemographic status, and duration and intensity of the protocol [The Fall risk analyses were conducted according to the intention-to-treat by including all women up to their last confirmed fall information, regardless of their exercise adherence. The predefined statistical analysis was conducted by an unblinded researcher who had access to the outcome data. All available cases were included in the follow-up analyses of clinical measurement data. Chi-square test was used to compare proportion of women with any fall and fall injury between groups. Incidence rate ratios (IRR) were obtained using Poisson regression analysis with a 95% confidence interval (CI) for multiple falls and contributing fall mechanisms. Fracture IRR and survival curves were analysed using the Poisson regression model and Kaplan–Meier curves with Log-rank test, respectively.
