Results of univariate and multivariate analysis in the training set are shown in Table Univariate and multivariate logistic analysis for risk factors of CIP in training set.Abbreviations: ALC, absolute lymphocyte count; CIP, checkpoint inhibitor‐related pneumonitis; ECOG PS, Eastern Cooperative Oncology Group, performance status; NLR, neutrophil to lymphocyte ratio; TNM, tumor node metastasis; WBC, white blood cell count.Similarly, the univariate and multivariate analysis of the testing set demonstrate that age, ECOG PS, history of prior radiotherapy, WBC, and ALC are potent predictors of the occurrence of CIP (Univariate and multivariate logistic analysis for risk factors of CIP in testing set.Abbreviations: ALC, absolute lymphocyte count; CIP, checkpoint inhibitor‐related pneumonitis; ECOG PS, Eastern Cooperative Oncology Group, performance status; NLR, neutrophil to lymphocyte ratio; TNM, tumor nodal metastasis; WBC, white blood cell count.
