Data are expressed as mean±standard deviation or numbers (%).

The p value was derived from independent t-test or χ2 test.

BP = blood pressure; DBP = diastolic blood pressure; L = left-arm BP; R = right-arm BP; SBP = systolic blood pressure.

*Normal was defined as SBP <120 mmHg and DBP <80 mmHg; Prehypertension was defined as 120 mmHg≤ SBP <140 mmHg or 80 mmHg≤ DBP <90 mmHg among non-hypertensive people; Hypertension was defined as SBP ≥140 mmHg or DBP ≥90 mmHg.
