Multivariate proportional hazard models predicting all-cause mortality by the teeth groups

	Exposure	Hazard ratio (95% confidence interval)	p-value
Model 1	group 1 (Nteeth=0)	1.0 (reference)	–
	group 2 ((0 < Nteeth ≤ 10)	0.99 (0.61–1.16)	0.95
	group 3 (10< Nteeth ≤ 20)	0.69 (0.36–1.30)	0.25

Model 1 simultaneously adjusted for age, sex, smoking (never, past and current).

Model 2 simultaneously adjusted for age, sex, smoking (never, past and current), hypertension, Total/HDL cholesterol ratio, diabetes, and education (in years).

Model 3 simultaneously adjusted all covariates in model 2 plus CRP >3 mg/L.

Model 4 simultaneously adjusted all covariates in model 2 plus fibrinogen > median (3.0 g/L).
