  • NOTE: In the Cox proportional hazard model, Eastern Cooperative Oncology Group, LDH and meanSUVmax/tumor stage (groups 1, 2, 3) were included as variables and group 1 (the LD with low SUV) was treated as the reference group.

    Abbreviations: Low SUV, meanSUVmax <8.7; high SUV, meanSUVmax ≥8.7; HR, hazard ratio; OS, overall survival; PFS, progression-free survival.
