Table 2. Adjusted Cox proportional-hazards regression models for the association of baseline WC categories with CVD mortality and all-cause mortality in an elderly Chinese population.

Baseline WC	Person-years	CVD mortality				All-cause mortality
Baseline WC	Person-years	Events	Mortality	^*Model1	^†Model2	Events	Mortality	^*Model1	^†Model2
^*Model1: adjusted for age, living alone, smoking status, alcohol consumption, physical activity, history of hypertension and diabetes mellitus. ^†Model2: Model1 + further adjusted for body mass index, systolic blood pressure, diastolic blood pressure, resting heart rate, fasting plasma glucose, total cholesterol, triglyceride, and high-density lipoprotein cholesterol. CVD: cardiovascular disease; WC: waist circumference.
