* poorly cohesive adenocarcinoma/diffuse-type carcinoma; ** intestinal-type adenocarcinoma. a, Chi-square test, Yates’ continuity corrected chi-square test, or Fisher’s exact test if appropriate; b, Mann–Whitney. NS = not statistically different. The characteristics of the patients included in the cohort were already reported in ref. [29].
