ADIPOQ and metabolic syndrome: When metabolic traits were classified as binary traits (Table 2), serum adiponectin concentration was negatively associated with dyslipidemia (OR = 0.75, 95% CI = 0.67–0.84, p = 1.00 × 10−6), normal weight vs. overweight (OR = 0.39, 95% CI = 0.33–0.46, p = 2.40 × 10−26), normal weight vs. obese (OR = 0.40, 95% CI = 0.34–0.47, p = 4.84 × 10−29), normal weight vs. overweight and obese participants (OR = 0.41, 95% CI = 0.36–0.47, p = 7.76 × 10−40).
