Table 4.

Differences in Survival by Sex, Stage, and Decade of Diagnosis. These are estimated from the accelerated failure time survival model which included the covariates diagnosis decade, age at diagnosis, race and origin, sex, Lymphoma Ann Arbor Stage, rurality, and SES index. Tukey-adjusted p-values are shown.
