In GEPIA, we confirmed that the OS of stomach adenocarcinoma (STAD) patients with a high level of CDH11 expression compared with the low-level group had statistical significance (P < 0.05, Figure 2(a)), but there were no significant relationships with PAAD, COAD (Figures 2(b) and 2(c)), and other types of cancers (Figure S2). The gene discussed is CDH11; the disease is gastric adenocarcinoma.
