Survival Curve from Scientific Research

KaplanMeier curves of OS in the full population (left), RAS / RAF mutant population (middle) and KRAS exon_2_mut population (right), stratified according to the presence (red) or absence (black) of a KRAS G12 mutation. Censoring events are indicated by vertical bars on the corresponding curve. The dotted lines indicate the subgroup-specific median OS. The table underneath each plot denotes the numbers at risk. Two-sided Wald test-based P values are shown. a Unadjusted by univariate Cox regression. b Adjusted by stratified, multivariate Cox regression, adjusted for eight baseline characteristics ( Methods ). Note that all Cox regression models passed the proportional-hazards assumption. OS, overall survival.
