Multivariate analysis for the PFS and OS
Multivariate analysis showed revealed that the PFS is significantly correlated with the BMI, EGFR mutation status, and GRIm-Score but not with PP, while the OS is significantly correlated with the ECOG-PS, BMI, number of organs involved in metastasis, EGFR mutation status, osimertinib use in the clinical course, GRIm-Score, and PP (Table 2 ).
