Receiver operating curve (ROC) for HCH versus CKD stage. The center diamond line represents the True Positive Fraction (TPF) for HCH compared to the stage of CKD. The upper and lower gray lines represent the 95% confidence levels. The Y axis = True Positive Fraction (i.e. Sensitivity) versus the X axis for False Positive Fraction (i.e. 1-specificity).
