This analysis included individuals more insulin resistant (tertile 1). The cutoff values of WC, BMI and WHtR were based on values already described in the literature and cutoff values of CI and LAP were chosen according to sensibility and specificity analysis. AUC: area under the curve. Comparisons between AUC (all patients) of body adiposity markers: WC vs. WHtR (p = 0.50), WC vs. CI (p = 0.21), WC vs. LAP (p = 0.63), WC vs. BMI (p = 0.09), WHtR vs. CI (p = 0.62), WHtR vs. LAP (p = 0.87), WHtR vs. BMI (p < 0.01), CI vs. LAP (p = 0.74), CI vs. BMI (p = 0.09), and LAP vs. BMI (p = 0.07).
