Analysis of (A) time‐to‐treatment discontinuation and (B) overall survival by multivariable Cox proportional hazards models. For each demographic or clinical variable, other variables were adjusted in the Cox proportional hazards models. For each analyzed variable, one subgroup was set as the reference group, and the other subgroups were compared with the reference group. The adjusted hazards ratio with 95% confidence internal and the p values are shown. * <0.05, **<0.005. Abbreviations: AIC, akaike information criterion; ALK, anaplastic lymphoma kinase; EGFR, epidermal growth factor receptor; NOS, not otherwise specified; NSCLC, non‐small cell lung cancer; PD‐L1, programmed cell death‐ligand 1.
