All-cause mortality rate
Never	reference	reference	reference
Sometimes	0.89 (0.80, 1.00)	0.92 (0.82, 1.04)	0.93 (0.82, 1.04)
Always	1.01 (0.83, 1.22)	0.94 (0.78, 1.15)	0.93 (0.76, 1.13)
Death-censored graft loss rate
Never	reference	reference	reference
Sometimes	0.95 (0.83, 1.08)	0.98 (0.86, 1.13)	0.98 (0.86, 1.13)
Always	0.74 (0.57, 0.96)	0.71 (0.54, 0.92)	0.71 (0.54, 0.92)

Crude and adjusted incidence rate ratios (cIRR and aIRR) with 95% confidence intervals (CI) are presented from Poisson regression models. Demographic + health factor models adjusted for center-mean demographic (% older, % female, % Black, % Hispanic) and health factors (% with diabetes, % undergoing dialysis, % living donor transplant); demographic + health + social factor models additionally adjusted for center-mean social factors (% low education, % working for income). Associations that are statistically significant at p < 0.05 are bolded
