KRAS and neoplasm: For patients with a KRAS mutated tumor and patients with a KRAS wild-type tumor, aspirin use after diagnosis was associated with an improved overall survival in the multivariate analysis (KRAS wild-type RR 0.68 (0.67 95%CI 0.47–0.97) and KRAS mutant RR 0.56 (95% CI 0.34–0.93)), (Table 2, Fig 3).
