 Consequences of falls and estimates of effect intervention (two year balance training programme for prevention of fall induced injuries) in women aged 75-85

Consequences	Control (n=354)	Exercise (n=352)	HR* (95% CI)
Total No of falls (rate†)	640 (0.92)	533 (0.79)	0.88 (0.77 to 1.00)
No of participants who had at least one fall	222	189	—
No of injurious falls (rate†):
Total	397 (0.56)	305 (0.45)	0.81 (0.67 to 0.99)
Moderate	310 (0.44)	237 (0.35)	0.81 (0.65 to 1.00)
Serious	87 (0.12)	68 (0.10)	0.83 (0.60 to 1.16)
No of participants who had at least one injurious fall	189	170	—

*Hazard ratio (adjusted for centre) computed with a “shared frailty” model. All women were included in analysis until their last time point. Covariance for random effect: 0.17 (SE 0.04; P<0.001) for all falls; 0.53 (SE 0.09; P<0.001) for injurious falls; 0.57 (SE 0.10; P<0.001) for moderate injurious falls; 0.35 (SE 0.25; P=0.30) for severe injurious falls.

†Rate per woman year=total number of events (fall related outcomes) divided by total number of woman years of follow-up in each group.
