Health and HRQL outcomes	6 month intervention effect (95% CI)	12 month intervention effect (95% CI)
Physical Component Score (PCS)
Control for baseline PCS only	0.25 (−0.67, 1.17)	−0.13 (−0.94,0.68)

Control for baseline PCS, risk factors, and demographics	0.33 (−0.51, 1.17)	0.06 (−0.61, 0.72)
N	1,011	990
Mental Component Score (MCS)
Control for baseline MCS only	0.56** (0.06, 1.06)	0.15 (−0.60, 0.90)
N	1,066	1,042
Control for baseline MCS, risk factors, and demographics	0.58* (−0.06, 1.21)	0.16 (−0.56, 0.88)
N	1,011	990
SF-6D
Control for baseline SF-6D only	0.01*** (0.01, 0.01)	0.01 (−0.01, 0.01)
N	1,070	1,047
Control for baseline SF-6D, risk factors, and demographics	0.01*** (0.01, 0.02)	0.01** (0.01, 0.01)
N	1,015	995
Geriatric Depression Scale (GDS)
Control for baseline MCS only		0.07 (−0.05, 0.20)
N		1,002
Control for baseline MCS, risk factors, and demographics		0.14** (0.01, 0.26)
N		953

Notes:

^*indicates p<0.10,

^**p<0.05,

^***p<0.01.

¹The Geriatric Depression Scale was reverse coded so that higher values indicated fewer depressive symptoms.

Regression models controlled for either: 1) only the baseline value of the outcome, or 2) risk factors and demographic covariates listed in Table 1, as well as the baseline value of the dependent variable (with the exception of the Geriatric Depression Scale regression, which controlled for baseline MCS score instead).
