Survival differences between 1990-2000 and 2001-2011 in African American and Caucasian women with stage I-III and stage IV breast cancer. Kaplan-Meier survival curves for Caucasian patients and African American patients with A. stage I-III disease and B. stage IV disease diagnosed in the years 1990-2000 and 2001-2011. Differences in Cox hazard ratios were determined using the logrank test. Differences were considered significant at P ≤ 0.05. Patients at risk are shown at 0, 24, 48, 72, 96 and 120 months, except in some instances where there were no deaths and alternate times are inserted in parentheses.
