For researchers submitting trial data to ClinicalTrials.gov, the Adverse Events module is one of four mandatory results sections. It requires reporting in three primary categories: All-Cause Mortality: A table tracking all deaths that occurred during the study, regardless of cause. Serious Adverse Events (SAEs): A tabular summary of events resulting in death, life-threatening conditions, hospitalization, or significant disability. Other Adverse Events: A table for non-serious events that exceed a specific frequency threshold, such as 5% within any study arm.
Adverse Events Module path is as follows:
Study -> Results Section -> Adverse Events Module -> Event Groups
Study -> Results Section -> Adverse Events Module -> Serious Events
Study -> Results Section -> Adverse Events Module -> Other Events

|---|---|---|---|---|---|---|---|---|
| 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). | None | None | 76 | 832 | 46 | 832 | View |
| 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). | None | None | 22 | 435 | 13 | 435 | View |
