Three independent SNPs in mitotic phase-related pathway genes predict NSCLC survival. Kaplan-Meier (KM) survival curves for NSCLC patients of three identified SNPs and combined unfavorable genotypes in the PLCO trial: (A) 0, 1, 2, and 3 unfavorable genotypes in OS; (B) Dichotomized groups of the unfavorable genotypes into 0–1 and 2–3 in OS; (C) 0, 1, 2, and 3 unfavorable genotyes in DSS; (D) Dichotomized groups of the unfavorable genotypes into 0–1 and 2–3 in DSS.
