SMR standardized mortality ratio, OS overall survival, PFS progression-free survival.

aActual 3- or 5-year OS was defined as subsequent OS of patients who achieved or failed to achieve PFS at 12, 24 or 36 months after initial treatment based on patients with ENKTCL vs. expected 3- or 5-year OS based on age-, sex- and country-matched general population data.

bCompared with the age- and sex-matched general Chinese population.
