  • T1–T3, averaged ba-PWV values were divided into three tertiles: ≤1256 cm/s, 1257–1448 cm/s, >1448 cm/s; right ba-PWV values were divided into ≤1260 cm/s, 1261–1456 cm/s, >1457 cm/s; left ba-PWV values were divided into ≤1248 cm/s, 1249–1442 cm/s, >1443 cm/s.

  • Model 1 was adjusted for age, sex. Model 2 was further adjusted for marital status (yes or no), smoking status (never, past and current), drinking status (never, past and current), BMI (kg/m2), FPG (mmol/L), TC (mmol/L), HDL-C (mmol/L). Model 3 was adjusted for the factors of model 2 plus hypertension, heart rate (beats/min).

  • Ba-PWV, brachial-ankle pulse wave velocity; BMI, body mass index; FPG, fasting plasma glucose; HDL-C, high-density lipoprotein cholesterol; TC, total cholesterol; T2DM, type 2 diabetes mellitus.
