Values present mean (SD) for continuous variables and frequency (%) for categorical variables. P values show statistical differences based on t test and χ2 test for continuous and categorical variables, respectively. BMI indicates body mass index; CVD, cardiovascular disease; DBP, diastolic blood pressure; FPG, fasting plasma glucose; HDL‐C, high‐density lipoprotein cholesterol; Ln‐triglycerides, natural log of triglyceride; SBP, systolic blood pressure; TC, total cholesterol; and WC, waist circumference.
Nonparticipants included those with missing data on hypertension status at baseline, individuals without any follow‐up data, and those with <3 times of participation in the study.
