tHcy level and the incident of MetS at cross-sectional follow-up.

Notes: Levels of tHcy were Ln transformed to normalize their distributions. Data were presented as ORs (per SD increase in LntHcy level) and corresponding 95% CIs. In the logistic regression model, MetS was treated as the dependent variable (MetS versus NonMetS). Model1: adjust for age, sex; Model2: adjust for age, sex, smoking, alcohol use, TC, LDL-C, UA, Cr, and eGFR; a: adjust for age, sex, smoking, alcohol use, UA, Cr, and eGFR. BMI: ≥25.0 kg/M2; Hypertension: systolic blood pressure (SBP) ≥140 mmHg, or diastolic blood pressure (DBP) ≥90 mmHg, or previously diagnosed as hypertension; Hyperglycemia: fasting blood-glucose (FPG) ≥6.1 mmol/L (110 mg/dl), or 2 h postprandial glucose (PG) ≥7.8 mmol/L (140 mg/dl), or previously diagnosed as hyperglycemia; Dyslipidemia: fasting triglycerides (TG) ≥1.7 mmol/L (150 mg/dl), or fasting HDL-C<0.9 mmol/L (35 mg/dl).
Abbreviations: BMI, body mass index; TC, total cholesterol; LDL-C, low density lipoprotein cholesterol; tHcy, total homocysteine; UA, uric acid; Cr, Creatinine; eGFR, estimated glomerular filtration rate; MetS, metabolic syndrome.

注：对总同型半胱氨酸（total homocysteine, tHcy）水平进行自然对数变换以使其分布趋于正态化。数据以比值比（OR，对应对数转换后总同型半胱氨酸水平每升高1个标准差）及相应的95%置信区间（95% CI）呈现。在logistic回归模型中，以代谢综合征（metabolic syndrome, MetS）作为因变量（代谢综合征组 vs 非代谢综合征组）。模型1：校正年龄、性别；模型2：校正年龄、性别、吸烟情况、饮酒情况、总胆固醇（total cholesterol, TC）、低密度脂蛋白胆固醇（low density lipoprotein cholesterol, LDL-C）、尿酸（uric acid, UA）、肌酐（Creatinine, Cr）及估算肾小球滤过率（estimated glomerular filtration rate, eGFR）；校正项a：校正年龄、性别、吸烟情况、饮酒情况、UA、Cr及eGFR。体质量指数（body mass index, BMI）：≥25.0 kg/m²；高血压：收缩压（systolic blood pressure, SBP）≥140 mmHg，或舒张压（diastolic blood pressure, DBP）≥90 mmHg，或既往确诊高血压；高血糖：空腹血糖（fasting blood-glucose, FPG）≥6.1 mmol/L（110 mg/dl），或餐后2小时血糖（PG）≥7.8 mmol/L（140 mg/dl），或既往确诊高血糖；血脂异常：空腹甘油三酯（triglycerides, TG）≥1.7 mmol/L（150 mg/dl），或空腹高密度脂蛋白胆固醇（HDL-C）<0.9 mmol/L（35 mg/dl）。
缩略语：BMI：体质量指数（body mass index）；TC：总胆固醇（total cholesterol）；LDL-C：低密度脂蛋白胆固醇（low density lipoprotein cholesterol）；tHcy：总同型半胱氨酸（total homocysteine）；UA：尿酸（uric acid）；Cr：肌酐（Creatinine）；eGFR：估算肾小球滤过率（estimated glomerular filtration rate）；MetS：代谢综合征（metabolic syndrome）。
