OS and PFS for pd-DMR genes according to their methylation status. Kaplan-Meier curves for OS (left column) and PFS (right column) according to methylation status of the pd-DMR array probes mapping to the genes GPX3 (probe ID cg07699362), RBP1 (cg23363832), SPARC (cg25913233), and TGFBI (cg21034676). Methylation status was categorized into “low” and high” methylation as described in the “Results” section. Log-rank P values indicate results of univariate analysis comparing low and high methylation groups.
