* Missing values and the cases who had a history of cerebrovascular disease were excluded.
/ HR, hazard ratio adjusted for sex and category of age (40-49, 50-59, 60-69, 70-79, and 80+ years).
// Multivariate HR, hazard ratio adjusted for sex, different areas (Wuning, Shanggao, Gaoan and Jinxian County) and the factors listed in this table.
** CI, confidence interval.
¶ Category was according to criterion of WHO. SBP: systolic blood pressure (mmHg); DBP: diastolic blood pressure (mmHg).
# Normal (SBP<130 and DBP<85).
## High-normal (130 ≦ SBP ≦ 139 and/or 85 ≦ DBP ≦ 89).
### Hypertension (SBP ≧ 140 and/or DBP ≧ 90 and those who had histories of hypertension).
