CWP indicates coal workers’ pneumoconiosis; baPWV, brachial-ankle pulse wave velocity
aBe defined as having the history of hypertension or SBP ≥ 140 mmHg or DBP ≥90 mmHg measured at the examination
bBe defined as having the history of diabetes mellitus or fasting blood glucose ≥7.0 mmol/L measured at the examination
