Notes: HTN, hypertension; BMI, body mass index; FBG, fasting blood glucose; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; BUN, blood urea nitrogen. The enumeration data were expressed as percentage form and analyzed by chi-square test, and the measurement data were expressed as mean ± standard deviation, comparisons between two groups were conducted by t-test.
