Figure 1 Receiver operating characteristic curves for (A) cardiac troponin T (cTnT) and (B) cardiac troponin I (cTnI) in predicting initial hospitalization adverse events in patients with (dotted line) and without (solid line) renal insufficiency. The lines represent prognostic sensitivity and false positive rates at increasing threshold values. The AUC and standard error are shown for each curve and the upper-left inflection points are indicated by an arrow and the corresponding sensitivity and specificity are shown in Table 3.
