Baseline and 12-Month Scores on Primary Outcomes of Mobility-Related Disability

	Intervention (n = 168), mean (SD), n or n (%)		Control (n = 168), mean (SD), n or n (%)		12-month between-group difference adjusted for baseline (95% CI), p, n
	Baseline n = 168	12 month n = 146	Baseline n = 168	12 month n = 138
Performance of mobility tasks aShort Physical Performance Battery (continuous version), 0–3	2.03 (0.49), n = 168	2.16 (0.56), n = 140	1.91 (0.57), n = 168	2.00 (0.6), n = 133	b0.08 (− 0.01 to 0.17), p = 0.08, n = 273
Self-reported activity ease aActivity Measure Post Acute Care, sum of basic mobility and daily activity components, 0–200	118.2 (18.2), n = 167	118.5 (18.2) n = 137	116.0 (16.5), n = 167	116.2 (19.9), n = 134	b0.18 (−2.89 to 3.26), p = 0.91, n = 270
Self-reported participation aLate Life Disability Instrument, performance plus limitation scaled scores, 0–200	114.1 (20.7), n = 164	121.0 (24.5), n = 144	107.0 (24.5), n = 161	114.4 (25.6), n = 136	b1.37 (− 2.56 to 5.32), p = 0.49, n = 273
