队列1中4种血管健康指标分别对于冠心病风险的预测

Risk of coronary heart disease event in cohort 1 in groups classified by four arterial health indicators (high vs. low) and per 1-SD increase in them

Items	Binary (high vs. low)		Continuous (per 1-SD increase)
	Unadjusted	Multivariable-adjusted	Unadjusted		Multivariable-adjusted
Multivariable-adjusted model is adjusted for age, gender, smoking, alcohol use, body mass index, heart rate, mean arterial pressure, hypertension, diabetes mellitus, cerebral infarction at baseline and hyperlipoidemia. CF-PWV, carotid-femoral artery pulse wave velocity; CR-PWV, carotid-radial artery pulse wave velocity; ABI, ankle brachial index; CAVI, cardio-ankle vascular index; SD, standard deviation; CI, confidence interval; HR, hazard ratio.
