The effect of race/ethnicity on the risk of cancer associated thrombosis. Effect of race/ethnicity compared with non-Hispanic Whites on the incidence of PE only (A), PE+DVT (B), proximal DVT (C), and isolated distal DVT (D), accounting for the competing risk of death and other known risk factors, among California patients with cancer with 13 common cancers, 2005 to 2017. Cox proportional hazard regressions models, using Fine and Gray methodology to account for the competing risk of death, were stratified by cancer type and adjusted for sex, age at diagnosis, stage at diagnosis, initial treatment (chemotherapy, radiation, and surgery), neighborhood sociodemographic status at diagnosis, and health insurance at diagnosis or initial treatment.
