Forest plot and ROC curves of the models constructed based on BMI/HDL-C, TG/HDL-C, VAI, and WHTR. Correlation between quartile of BMI/HDL-C (A), TG/HDL-C (B), VAI (C), and WHTR (D) and MS with adjustment of different confounding factors. Different background of forest plot represents different confounding factor correction: Blue - without adjustment of confounding factors; red - adjustment of confounding factors including gender, education level, and smoking; yellow - adjustment of confounding factors including BMI, BFM, PBF, VFA, AMC, WC, SCR, LDH, TG, HDL-C, and insulin. Comparison of ROC curves (E) without adjustment of confounding factors; (F) with adjustment of confounding factors including gender, education level, and smoking; (G) with adjustment of confounding factors including BMI, BFM, PBF, VFA, AMC, WC, SCR, LDH, TG, HDL-C, and insulin. BMI, Body Mass Index; HDL-C, high-density lipoprotein cholesterol; TG, triglyceride; WHTR: waist-to-height ratio. VAI: visceral adiposity index
