Figure 2: Levels of plasma triglyceride in nonobese (waist girth <90 cm), overweight (waist girth 90 to 101 cm), and obese (≥102 cm) grouped according to low (<6.5 ng/mL) or high (≥6.5 ng/mL) adiponectin. Overweight men with high adiponectin levels have significantly () lower levels of plasma triglyceride compared with those with low adiponectin levels (a). However, after adjustment of adiponectin levels for leptin (ratio of adiponectin/leptin), levels of plasma triglycerides were significantly () lower in those with a high ratio of adiponectin/leptin, regardless of waist category (nonobese, overweight, or obese) (b). Similar analyses are shown for HDL C. Levels of plasma HDL C were significantly () higher in overweight and obese men having a high adiponectin level (c). However, HDL cholesterol levels were significantly higher () in nonobese men after grouping the subjects according to a low or high ratio of adiponectin/leptin (d).
