Fig. 3From: Genome-wide DNA methylation profiling of HPV-negative leukoplakia and gingivobuccal complex cancersKaplan–Meier (KM) plots and receiver operating characteristic (ROC) curve. KM plots for A CYB5A and B CASP4 losses were associated with poor recurrence free survival (RFS). ISG15 gain showed better C RFS, D Disease specific survival (DSS) and E Overall survival (OS). F illustrates the prognostic potential of ISG15 as analysed by a ROC curveBack to article page
