Fig 3. Receiver Operator Curve (ROC) Analysis of DNA Methylation Index and HPV.
ROC of predicted sensitivity and 1-specificity when DNA MI for DAPK1, RARB, SLIT2 and WIF1 genes was added to a model with HPV status and age. The test of the equality between AUC for HPV and age (AUC = 79%, dashed line) compared to methylation index for DAPK1, RARB, SLIT2 and WIF1, HPV, and age (AUC = 98%, solid line), p-value = 0.0002.
