However, in the Bayesian ranking, the risk of PD‐L1 inhibitors + chemotherapy occurring was least in the occurrence of any grade of AE (a in Figure S3); yet the risk of PD‐L1 inhibitors + chemotherapy occurring was biggest in grade ≥ 3 AE (b in Figure S3), the occurrence of treatment‐related neutropenia of any grade (c in Supplementary Figure 3) and neutropenia of grade 3 or higher (d in Figure S3). The gene discussed is CD274; the disease is Decreased total neutrophil count.
