Survival evaluation and comparison of survival between ER+/PgR+ group and ER−/PgR+ group with or without adjuvant TAM treatment

	Without TAM				With TAM

^aDFS was calculated from the date of first diagnostic biopsy or surgery to first recurrence of disease at a local, regional, or distant site; or to a second cancer; or to a death without evidence of cancer. OS was defined as the interval between the diagnostic biopsy or surgery and death from any cause

^bSurvival rates evaluated by life table evaluation

^c P value evaluated by log rank test
