ENPEP and cancer: No significant difference was shown in OS between the lower ENPEP expression group and the higher ENPEP expression group in a pooled cohort (pooled cohort: HR [95% CI] = 0.93 [0.85–1.02], p = 0.140, Figure S4), and except for LGG, MESO, KIRP, and KIRC, no significant results was observed, indicating that lower ENPEP expression was not influencing the prognosis of non‐ICIs treatment for most cancers.
