In the subgroup analysis among Hispanics, patients with breast cancer in El Paso, TX, were more likely to have advanced stages of BC (RRR = 2.15, P < 0.0001), less likely to have ER+/PR+ (RRR = 0.56, P < 0.0001), and more likely to have triple‐negative BC (RRR = 2.38, P < 0.0001) compared to the Loma Linda, CA, group.
