Text: Overall, no evidence of a benefit for ovarian ablation or suppression was observed for relapse-free survival (relapse in the ovarian ablation/suppression versus no ovarian ablation/suppression group, 290 events versus 306 events, HR = 0. 95, 95 % confidence interval [CI] = 0. 81 to 1. 12 ; P =. 56) or overall survival (death from any cause in the ovarian ablation or suppression versus no ovarian ablation/suppression group, 215 events versus 230 events, HR = 0. 94, 95 % CI = 0. 78 to 1. 13 ; P =. 44), nor were differences seen after adjustment for age, nodal status, or estrogen receptor (ER) status.
