Text: Hazard ratios (HRs) and 95 % confidence intervals (CIs) were as follows : (a) CMF versus HEC, HR = 1. 42 for HER-2-amplified tumors (95 % CI, 0. 54-3. 76 ; P = 0. 48) and 0. 84 for HER-2-nonamplified tumors (95 % CI, 0. 49-1. 44 ; P = 0. 53) ; (b) CMF versus EC, HR = 1. 65 for HER-2-amplified tumors (95 % CI, 0. 66-4. 13 ; P = 0. 29) and 0. 66 for HER-2-nonamplified tumors (95 % CI, 0. 39-1. 10 ; P = 0. 11) ; and (c) EC versus HEC, HR = 0. 93 for HER-2-amplified tumors (95 % CI, 0. 31-2. 77, P = 0. 90) and 1. 33 for HER-2-nonamplified tumors (95 % CI, 0. 82-2. 14 ; P = 0. 25).
