Data are presented as mean ± standard deviation for normally distributed continuous data, as median and inter‐quartile ranges for skew‐distributed continuous data and percentage (%) for categorical variables.
Hypertension: history of hypertension diagnosed and/or treated by a physician, or blood pressure >140 mm Hg systolic or >90 mm Hg diastolic on at least two measurements
Dyslipidemia: history of dyslipidemia treatment, or total cholesterol ≥200 mg/dl, low density lipoprotein ≥130 mg/dl, and high density lipoprotein <40 mg/dl.
