Basic clinical characteristics of all subjects at baseline.

BMI: body mass index; WHR: waist-hip ratio; SBP: systolic blood pressure; DBP: diastolic blood pressure; BUN: blood urea nitrogen; TC: total cholesterol; TG: triglycerides; HDL-C: high-density lipoprotein cholesterol; LDL-C: low density lipoprotein-cholesterol; FPG: fasting plasma glucose; 2h-PG: 2-h postprandial plasma glucose; HbA1c: glycosylated haemoglobin A1c; HOMA-IR: homeostasis model assessment of insulin resistance;*logarithmically transformed before analysis.BMI：身体质量指数（body mass index）；WHR：腰臀比（waist-hip ratio）；SBP：收缩压（systolic blood pressure）；DBP：舒张压（diastolic blood pressure）；BUN：血尿素氮（blood urea nitrogen）；TC：总胆固醇（total cholesterol）；TG：甘油三酯（triglycerides）；HDL-C：高密度脂蛋白胆固醇（high-density lipoprotein cholesterol）；LDL-C：低密度脂蛋白胆固醇（low density lipoprotein-cholesterol）；FPG：空腹血浆葡萄糖（fasting plasma glucose）；2h-PG：餐后2小时血浆葡萄糖（2-h postprandial plasma glucose）；HbA1c：糖化血红蛋白A1c（glycosylated haemoglobin A1c）；HOMA-IR：胰岛素抵抗稳态模型评估（homeostasis model assessment of insulin resistance）；*分析前需进行对数转换。
