ULBP2 and colon adenocarcinoma: Our prognostic survival curves showed that patients with negative expression of ULBP2 protein in COAD had a better OS and RFS (Figure 5G, 5H), and the results of Multivariate COX regression analysis showed that ULBP2 protein expression was related to COAD OS [adjusted P=0.047, HR (95% CI) =2.009 (1.009–4.001)], while ULBP2 protein expression was related to COAD RFS [adjusted P=0.032, HR (95% CI) =9.521 (1.217–74.469)] (Supplementary Table 5).
