Least squares mean Short Physical Performance Battery (SPPB) scores in points at 6 and 12 months only in persons with baseline CKDa.

Table 3: Least squares mean Short Physical Performance Battery (SPPB) scores in points at 6 and 12 months only in persons with baseline CKD^a.

	SPPB scores (95% CI)
Intervention	Baseline	6 months	12 months
Physical activity (N = 53)	7.65 (7.28,8.02)	8.44 (7.92,8.95)	8.25 (7.68,8.82)
Successful aging (N = 52)	7.19 (6.77,7.61)	7.73 (7.15,8.31)	7.43 (6.78,8.10)
P value	0.10	0.04	0.04
Overall p value	0.02

^aAdjusted for age, sex, diabetes, hypertension, site, visit, baseline SPPB score, and interaction of intervention and visit; P value for interaction of intervention with visit = 0.73; CKD: Chronic Kidney Disease; CI: Confidence Interval; PA: Physical Activity; SA: Successful Aging.
