  1. Data are summarized as mean (SD), median (interquartile range), and numbers (percentage) according to their data type and distribution
  2. LVH left ventricular hypertrophy, CNY Chinese currency, WC waist circumstance, BMI body mass index, SBP systolic blood pressure, DBP diastolic blood pressure, MBP mean blood pressure, FPG fasting plasma glucose, Scr serum creatinine, TC total cholesterol, TG triglyceride, LDL-C low-density lipoprotein cholesterol, HDL-C high-density lipoprotein cholesterol, IVST interventricular septum thickness, LVEDd left ventricular end-diastolic diameter, PWT posterior wall thickness, LVM left ventricular mass, LVMI left ventricular mass index, ePWV estimated pulse wave velocity
  3. *Chi-square test or Rank-sum test were employed to compare categorical variables between groups. Student's t test or Mann–Whitney test were employed to compare continuous data between groups
