Table 2 shows that in several cases HR was found to be smaller than 0.5 or largely higher than 1.5, suggesting a very strong association of the expression to the survival, as for instance for PD-1 (PDCD1) expression in Uterine Corpus Endometrial Carcinoma (UCEC) (see the corresponding Kaplan–Meier plots in Fig. 4A), or for TIGIT expression in Thymoma (THYM) (see the corresponding Kaplan–Meier plots in Fig. 4B). Here, PDCD1 is linked to endometrial carcinoma.
