Figure 2 (A) ROC curves of the true-positive rate (sensitivity) versus the false-positive rate (1–specificity) for HOMA insulin resistance. The smooth curves are model-fitted curves by the method of Swets (26). (B) Two-graph ROC plots of the sensitivity (solid lines) and specificity (dotted lines) curves from the ROC curve analysis versus HOMA insulin resistance. Cutoff values were defined to give 70% specificity.
