OS was defined as the time from date of relapse or stage IV disease (index date) to death at any cause. Participants were censored for OS by 1 February 2024.

Each comorbidity recorded for participant, had score between 0 to 6 as per comorbidity burden, if it was part of CCI. Higher score=more severe comorbidity status. CCI score 0:participants with no comorbidity besides BC disease, CCI score 1:participant with one comorbidity with score of 1,e.g.,myocardial infarction or diabetes mellitus(DM), CCI score 2:participant with two comorbidities each classified with score of 1 or one single comorbidity classified with score of 2,e.g.,DM with organ damage, CCI score of 3or higher: participant with severe comorbidity, i.e. those having one comorbidity classified with score of 6(e.g., Human Immunodeficiency Virus/Acquired Immuno Deficiency Syndrome),or two or more comorbidities each classified with scores of1-2,all in addition to participant's BC disease. Index date=date of relapse or stage IV disease.

OS: time from date of relapse or stage IV disease to death at any cause. CCI was used as data source for comorbidity in study.

PFS was defined as the time from the index date to progression or death, whichever occurred first. Participants were censored for PFS by 1 February 2024. Progression was based on radiological, clinical, and biochemical examination from the treating departments. Comorbidities were categorized into five main disease groups: cardiac disease, vascular disease, metabolic disease, psychiatric disease and blood and lymphatic system. Results for cardiac disease, vascular disease and metabolic disease have been reported in this outcome measure. Index date was the date of relapse or stage IV disease. Stage IV disease means that the cancer has spread to distant parts of the body.

Visceral disease status was defined as metastases in the visceral organs, e.g., lung, liver. Non-visceral disease status was defined as metastases in the non-visceral organs, e.g., bone, skin, lymph nodes. PFS in participants with visceral and non-visceral disease status is reported in this outcome measure. Index date was the date of relapse or stage IV disease.

PFS was defined as the time from the index date to progression or death, whichever occurred first. Progression of disease was based on scans and blood testing results. Disease progression was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Kaplan-Meier method was used for analysis.
