Groups did not differ in the proportion of single fallers ( 28 % vs 24 % ; OR , 1.24 ; 95 % CI , 0.64-2 .42 ; P = .52 ) , but more participants in the treatment group had multiple falls ( 49 % vs 35 % ; OR , 1.83 ; 95 % CI , 1.01-3 .33 ; P = .047 ) ; however , this difference was no longer significant when adjusted for baseline frailty .
