*The Cox proportional hazard model was fitted followed by backward variable elimination with a significance level of p<0.1. The covariables controlled for included age, sex, race, baseline Body Mass Index, sites of metastases, ECOG performance status, clear cell histology and prior lines of therapy.
†Statistical significance at alpha<0.05.
ECOG, Eastern Cooperative Oncology Group; mGPS, modified Glasgow Prognostic Score; MVA, multivariate analysis; OS, overall survival; PFS, progression-free survival; UVA, univariate analysis.
