Cox regression models of the hazards of death in the non-CKD and CKD subpopulations according to CS

	Model 1	Model 2	Model 3
Non-CKD subpopulation
CS = 11	reference	reference	reference
CS = 9–10	1.51 (1.24–1.86)	1.20 (0.99–1.47)	1.19 (0.98–1.45)
CS = 6–8	2.07 (1.64–2.60)	1.25 (0.93–1.68)	1.18 (0.89–1.56)
CS = 0–5	3.58 (2.69–4.77)	1.46 (1.07–2.01)	1.39 (1.00–1.93)
CKD subpopulation
CS = 11	reference	reference	reference
CS = 9–10	1.41 (1.03–1.92)	1.16 (0.83–1.62)	1.14 (0.80–1.62)
CS = 6–8	1.62 (1.16–2.26)	1.24 (0.85–1.80)	1.24 (0.85–1.80)
CS = 0–5	3.47 (2.53–4.75)	2.03 (1.16–3.55)	2.02 (1.11–3.67)

Model 1: Unadjusted.

Model 2: Adjusted for demographic factors, history of cardiovascular disease, hypertension, diabetes, physical inactivity, smoking, alcohol use, eGFR and albuminuria; stratified by gender and history of stroke.

Model 3: Model 2 variables plus CRP, hemoglobin, and serum 25-hydroxyvitamin D; stratified by gender and history of stroke.
