Kaplan–Meier survival analyses and forest plot according to gene mutation status. Correlation between the pathway mutations and progression-free survival (a). wt, wild-type; RAS mt, RAS mutated; RAF mt, RAF mutated. Forest plot of Cox proportional hazards regression with RAS/RAF mutation status and PIK3CA. mutation status (b). p-value < 0.05 is highlighted with one asterisk
