Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Between June 1997 and June 1999, 1491 women from 20 countries were enrolled in the study. The last patient last visit occurred in January 2010.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Eleven women (1 who had been randomly assigned to receive TAC and 10 assigned to receive FAC) did not receive any treatment for the following reasons: 8 withdrew consent, 1 was lost to follow-up, and 2 did not receive treatment for other reasons. In total 1480 patients (744 in the TAC group and 736 in the FAC group) were treated.
