^a Neighborhood percent Hispanic population was centered at the mean. HR = hazard ratio; aHR = adjusted hazard ratio; CI: confidence interval. Models 2 and 3 include age, sex, tumor grade, tumor stage, year of diagnosis, tumor histology, urban/rural status, and mammography capacity. Dashes (–) indicate that the variables were not entered into the model.
