WC	0.873	0.890	0.851	0.875
MAP	0.737	0.675	0.693	0.635
TG/HDL-C^#	0.792	0.786	0.820	0.804
Leptin/Adiponectin^#	-	0.842	-	0.869

Abbreviations: WC waist circumference, MAP mean arterial pressure, TG triglycerides, HDL-C high-density lipoprotein cholesterol, TG/HDL TG-to-HDL ratio, HOMA-IR homeostatic model assessment of insulin resistance, Leptin/Adiponectin leptin-to-adiponectin ratio. ^# Skewed distributions were logarithmically transformed. Factors with an eigenvalue ≥1 were selected for analysis.
