At each analysis, a step-down screening process was used. We in comparison the AC-T group with each trastuzumab-containing routine at a significance level add up to one half alpha to account for multiple examining. If both comparisons had been significant, we compared the two trastuzumab regimens at a significance equal to alpha. The first interim analysis was carried out after the observation of 322 disease-free survival events in September 2005. At that right period, the efficacy boundaries were crossed and demonstrated a significant difference in disease-free survival occasions in favor of both AC-T plus trastuzumab and TCH, in comparison with AC-T, with no significant difference between AC-T plus trastuzumab and TCH.
