The associations between physical activity and time to first fall and time to recurrent falling

Model	HR	95%CI	p value
Time to first fall
Physical activity	0.98	0.96–1.01	0.13
Physical activity + confounders	0.98	0.96–1.00	0.11
Time to recurrent falling
Physical activity	0.93	0.90–0.97	<0.001
Physical activity + confounders	0.96	0.92–0.99	0.02

Hazard Ratios (HR) and 95% Confidence Interval (95%CI) are presented per 100 units (i.e., minutes per day × MET score) increase in physical activity. Confounders were age, sex, body mass index, chronic diseases, psychotropic medication, mini-mental state examination, depressive symptoms, and fear of falling
