Survival analysis associated with the genes in Radiosensitivity-Related Prognostic Risk Signature (RRPRS). Kaplan–Meier plots with the PFS probability of the patients according to stratification by the expression levels of each individual gene. The ordinate axis represents the probability of survival (0–1), and the abscissa axis represents the PFS in days. Blue represents patients with gene expression levels below the median expression of the gene, and red represents patients with expression levels above the median
