  1. ESOM esomeprazole, DFI disease free survival; de novo metastatic: metastatic breast cancer is diagnosed when there is no prior history of breast cancer
  2. Demographic and baseline disease characteristics of the intention-to-treat population were generally well balanced between treatment arms (all p > 0.05)
