As demonstrated in Figures 2F–K, we observed a positive association between the expression of PD‐L1 and PD‐L1 network module scores in four immunotherapy cohorts, including three melanoma cohorts (Hugo et al.,[38] VanAllen et al.,[39] and Riaz et al.[40]) and one bladder cancer cohort (IMvigor210[41]). This evidence concerns the gene CD274 and urinary bladder carcinoma.
