Statistically significant. PFS, progression-free survival; OS, overall survival; RR, relative risk; CI, confidence interval; SUVmax, maximum standardized uptake value; SUVmean, mean standardized uptake value; MTVmax, metabolic tumor volume of the maximum lesion; MTVsum, sum of metabolic tumor volume; TLGmax, total lesion glycolysis of the maximum lesion; TLGsum, sum of total lesion glycolysis; Dmax, maximum diameter of the maximum lesion; CR, complete remission.
