Cumulative relative survival. (A) Cumulative relative survival restricted to patients younger than 65 years of age (n = 3123). (B) Cumulative relative survival restricted to patients 65 or older (n = 1206). Cumulative relative survival shows the ratio of the observed survival in the UAMS cohort, relative to the normal expected survival in the SEER life tables, matched on age, sex, year, and race/ethnicity. Downward sloping lines indicate consecutive years of follow-up where UAMS survival was worse compared with SEER survival. Lines that plateau indicate years where UAMS survival was similar to SEER survival and excess mortality from MM for the given years was approaching 0.
