Characteristics	pMMR-Mutant KRAS
	OR (95% CI)	P
Female (referent: male)	2.73 (1.69 to 4.85)	0.001
Proximal (referent: distal)	2.17 (1.39 to 3.33)	0.001
pN 1–2 (referent: pN 0)	4.95 (2.84 to 6.38)	0.003
Mucinous (referent: non-mucinous)	3.44 (1.11 to 7.47)	0.02
pTNM III–IV (referent: pTNM I–II)	0.26 (0.03 to 2.02)	0.19

CI = confidence interval; pMMR = proficient mismatch repair; OR = odds ratio.
