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
| Title | Description | Deaths # Affected | Deaths # At Risk | Serious # Affected | Serious # At Risk | Other # Affected | Other # At Risk | View |
|---|---|---|---|---|---|---|---|---|
| Arm I (SRS) | Patients undergo stereotactic radiosurgery (SRS) received 24 Gy in a single fraction if lesions were less than 2.0cm or 20 Gy if lesions were 2 to 2.9 cm in maximum diameter. | 5 | None | 8 | 68 | 45 | 68 | View |
| Arm II (SRS+WBRT) | Patients randomly assigned to SRS plus WBRT received 30 GY in 12 fractions of 2.5-Gy WBRT delivered 5 days a week. Whole brain radiotherapy began within 14 days of SRS. | 7 | None | 11 | 64 | 53 | 64 | View |
