ROC curves of HbA1c, insulin, glycemia and HOMA-IR for insulin resistance and criteria clusters.

<p>ROC curves for detecting insulin resistance, the metabolic syndrome, 2 or more, and 3 or more criteria for the metabolic syndrome other than the high glucose criterion. The small circles indicate the sensitivity and specificity when using the tertiles of each variable as cut-offs. For insulin resistance, the HOMA-IR curve can not be seen as it lies exactly at the left and upper borders.
