Figure 4.

Receiver operating characteristic (ROC) analysis for cTnI and cTnT for patient cases with impaired kidney function. ROC curves are shown for all patient cases with an eGFR > 60 mL/min/1.73 m² (A) and ≤ 60 mL/min/1.73 m² (B) distinctly. Analyses are based on the diagnosis of myocardial injury. Green curves are for cTnI with gender-specific cutoffs, red curves for cTnI with gender-unspecific cutoff and blue curves for cTnT. Calculated are area under the curves (AUC), optimized cutoffs (Youden Index) and sensitivities as well as specificities at the calculated cutoffs.
