FABP4 and obesity due to melanocortin 4 receptor deficiency: Additionally, the results of our logistic regression analysis showed that each 1 ng/dL increase in the A-FABP concentration significantly increased the probability of the occurrence of obesity, elevated TC/HDL-C ratio and TG/HDL-C ratio, and decreased HDL-C level even after multivariate adjustment, whereas all odds ratios became statistically insignificant after controlling for BMI in postmenopausal women.
