Daily-Life and Laboratory Falls
For the primary outcome, 62 falls in the PBT group (rate of falls per person-year of follow-up: 0.90; 95% CI, 0.58-1.21) and 78 in the control group (rate of falls per person-year of follow-up: 1.14; 95% CI, 0.76-1.52) were reported, resulting in a nonsignificant 22% relative between-group difference in fall rates (incidence rate ratio [IRR], 0.78; 95% CI, 0.48-1.27) (
