Adjusted 1 Cox regression: cox regression for year at diagnosis and race matched reconstruction types.

Adjusted 2 Cox regression: cox regression for year at diagnosis, race stage, ER status, PR status and HER2 status matched reconstruction types.

Adjusted 3 Cox regression: cox regression for age at diagnosis, year at diagnosis, sex, race, stage, ER status, PR status, HER2 status, radiation therapy and chemotherapy matched reconstruction types.
