Kaplan-Meier curve for the primary composite outcome event-free survival in the two groups. Plots of time until the primary composite outcome (death or any new fractures) in the intervention group and in the usual care group are shown. The Kaplan-Meier method was used to estimate the cumulative event rate. The log-rank test was used to assess the efficacy of polypharmacy intervention compared with usual care with respect to the primary composite outcome. Data for patients without an event were censored at the time of the last visit
