KRAS and colorectal carcinoma: A higher hPDI was associated with lower incidence of KRAS‐wildtype CRC (multivariable HR comparing extreme quartiles, 0.74, 95% CI: 0.57, 0.96; P‐trend = .004) but not KRAS‐mutant CRC (multivariable HR comparing extreme quartiles, 1.10, 95% CI: 0.82, 1.47; P‐trend = .22).
