Kaplan-Meier overall survival in BSC KRAS identifiable patients – by KRAS and switch status

Notes: BSC - Best Supportive Care; KRAS - Kirsten Rat Sarcoma Virus; MT - Mutant Type; WT - Wild Type. These curves cannot be used to compare survival because they are subject to immortal time bias. Curves are shown to illustrate poor prognosis in non-switchers: only 8 BSC non-switchers survived longer than 4 months
