In multivariate analysis with Cox proportional hazards regression method, we found that patients with PD-L1 expression on ≥1% of tumor cells compared to patients without PD-L1 expression on cancer cells had a significantly lower risk of death (HR=0.377, 95% CI: 0.1636–0.8688, p=0.022, Table 2). Here, CD274 is linked to cancer.
