CD274 and neoplasm: However, due to the different definitions of high expression in each study, we selected the highest PD‐L1 expression population (PD‐L1 expression level ≥ 10% in CheckMate 141, tumor proportion score ≥ 50% in KENOTE 040, combined positive score ≥ 20 in KENOTE 048, tumor cell PD‐L1 expression ≥50% or immune cells PD‐L1 expression ≥25% in KESTREL, tumor cell PD‐L1 expression ≥25% in EAGLE) for pooled analysis.
