Note. Adjusted hazard ratios are presented in bold font.
*
All models are adjusted for marital status, SEER registry, tumor size, tumor grade, node involvement, ER status, PR status, receipt of radiation treatment, and receipt of surgery unless otherwise noted
**
Adjusted for marital status and SEER registry only, because model failed to converge with other covariates added
