Recruitment Details

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
This study was conducted from 01 June 2008 to 31 December 2012 in the United States. A total of 1287 participants were enrolled.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Out of 1287 participants, 20 were not eligible for the study and were excluded. Of 1267 participants, 832 were observed in Chemotherapy cohort and 435 were observed in Hormonal Therapy cohort.

Reporting Groups

	Description
Chemotherapy Cohort	Eligible participants with human epidermal growth factor receptor 2-negative (HER2-negative) disease who received their first cytotoxic chemotherapy and/or targeted therapy were observed until death, withdrawal of consent, loss to follow-up, or until study closure, whichever was sooner (approximately 4.5 years).
Hormonal Therapy Cohort	Eligible participants with hormone receptor positive disease who received their first hormonal therapy for advanced disease were observed until death, withdrawal of consent, loss to follow-up, or until study closure, whichever was sooner (approximately 4.5 years).

Population Description

Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Baseline characteristics was analyzed for all enrolled participants in respective individual groups (CT Cohort and HT Cohort); therefore, the data for 'mean age' for total population is not applicable for this study.

Reporting Groups

	Description
Chemotherapy Cohort	Eligible participants with HER2-negative disease who received their first cytotoxic chemotherapy and/or targeted therapy were observed until death, withdrawal of consent, loss to follow-up, or until study closure, whichever was sooner (approximately 4.5 years).
Hormonal Therapy Cohort	Eligible participants with hormone receptor positive disease who received their first hormonal therapy for advanced disease were observed until death, withdrawal of consent, loss to follow-up, or until study closure, whichever was sooner (approximately 4.5 years).
