* Stratified by stage and age at diagnosis with adjustment for sex, cancer-directed surgery, and radiation therapy and interaction between race/ethnicity and SES. Referent: Non-Hispanic white (NHW) cases in same SES strata. Overall model interaction term P value for lung = .11, liver = .97, kidney = .09, colorectal = .05, prostate = .13, breast = 0. Absolute difference (AD) in survival compared with NHWs. A negative value indicates that survival was higher than in the NHW group. API = Asian/Pacific Islander; CRC = colorectal cancer; HISP = Hispanic; NHB = non-Hispanic black; Q = quintile; RD = relative disparity.
† P < .05.
