Elevated UACR was defined as a UACR ≥3 mg/mmol. Data were means ± SD or medians (interquartile range) for skewed variables or proportions for categorical variables. Student’s -test was used to evaluate differences in mean and chi-square test to evaluate differences in proportions.
MetS: metabolic syndrome; SBP: systolic blood pressure; DBP: diastolic blood pressure; BMI: body mass index; FPG: fasting plasma glucose; TG: triglyceride; TC: total cholesterol; HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol; UACR: urinary albumin-creatinine ratio; eGFR: estimated glomerular filtration rate.
