The event of interest is breast cancer-related death among triple negative breast cancer patients in Louisiana, diagnosed 2010–2012. HR, hazard ratio; CI, confidence interval; SEER, Surveillance, Epidemiology and End Results Program; CDI, concentrated disadvantage index; SD, standard deviation.
Model 1 is adjusted for SEER stage, age and race. Model 2 is adjusted for SEER stage, age, race and CDI.
Models include random intercept (frailty term) for US census tracts.
