## Figure 4.
Receiver operating curve (ROC) curve for PTH, PO4 and serum albumin versus HCH. The center diamond line represents the true positive fraction(TPF) for HCH in patients
with a calculated sum for the linear predictor defined as the linear combination for
PTH, PO4 and albumin. 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).
