In this cohort, PD-L1 CPS was positively correlated with tumor shrinkage (r = 0.941; 95% CI: 0.739 to 0.988; p < 0.001) and negatively correlated with both operative time (r = −0.952; 95% CI −0.990 to −0.783; p < 0.001) and blood loss (r = −0.861; 95% CI: −0.970 to −0.458; p = 0.003) (Supplementary Table 2). The gene discussed is CD274; the disease is neoplasm.
