Authors’ analysis of the 2006 to 2013 SEER-Medicaid data. All regression models also controlled for age at diagnosis, sex, race/ethnicity, year of diagnosis, rurality of residence, and neighborhood-level SES, as appropriate, as well as SEER cancer registries. Standard errors were clustered by SEER cancer registries.
Ref., reference group.
Three observations were dropped from the regression model because of the perfect prediction issue (ie, only 1 non-Hispanic Black patient was in the Hawaii registry who had stage IV lymphoma at diagnosis, and none of the 2 non-Hispanic Black patients in the Utah registry had stage IV lymphoma at diagnosis).
One observation was dropped from the regression model because of the perfect prediction issue (ie, only 1 Hispanic patient was in the Kentucky registry who did not have stage IV lymphoma at diagnosis).
