The results of the Hosmer-Lemeshow test and the AUROC are in italics to differentiate them from the ORs.
*Category ‘others’ includes blood samples.
ALK, anaplastic lymphoma kinase; AUROC, area under receiver operating characteristic curve; EGFR, epidermal growth factor receptor; FNA, fine-needle aspiration; NSCLC-NOS, non-small cell lung cancer–not otherwise specified; PD-L1, programmed death ligand-1; ref., reference; ROS1, c-ros oncogene 1.
