From: Highly frequent promoter methylation and PIK3CA amplification in non-small cell lung cancer (NSCLC)
Receiver operating characteristic (ROC) curves for the 6 genes in NSCLC. Complete DNA methylation data from all NSCLC and non-cancerous lung tissues were used to construct the ROC curves. The ROC curves plot sensitivity vs. 100-specificity. The determined cut-off values for CALCA, CDH1, DAPK1, EVX2, PAX6, and RASSF1A were 45.7, 29.0, 0, 23.7, 13.0, and 0, respectively.
