Overall survival of nivolumab-treated patients according to changes in [18F]-fluoro-2-deoxy-D-glucose positron emission tomography/MRI parameters. Kaplan-Meier curves of overall survival stratified by Δdiameter (A), total lesion glycolysis (ΔTLG) (B), apparent diffusion coefficient (ΔADC)mean (C) and ΔTLG+ΔADCmean (D), with cut-off values determined by receiver operating characteristic curve analysis.
