Data expressed as HR (95% CI)
All models adjusted for accelerometer wear time
Model 1 stratifies for site and sex, and adjusts for randomization
Model 2 adjusted for model 1, race, age, and education
Model 3 adjusted for model 2, baseline Short Physical Performance Battery Score, baseline 400 m walking speed, and co-morbidity burden
Model 4 adjusted for model 3, use of anti-hypertensive and lipid-lowering drugs, sleep quality, and depression
Bold if p-value < 0.004 (Bonferroni corrected for multiple accelerometry measures and mobility outcomes)
