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 B (Radiotherapy IMRT 50 Gy) | Patients with intermediate risk undergo low-dose (50Gy) intensity modulated radiation therapy (IMRT) once daily (QD) over 25 fractions. | 4 | None | 17 | 120 | 57 | 120 | View |
| Arm C (Radiotherapy IMRT 60 Gy) | Patients with intermediate risk undergo standard-dose (60Gy) IMRT QD over 30 fractions. | 7 | None | 31 | 127 | 71 | 127 | View |
| Arm D (Cisplatin + IMRT 66 Gy) | High risk patients receive IMRT at 66 Gy QD for 33 fractions. Patients also receive cisplatin intravenously (IV) over 60 minutes on days 1, 8, 15, 22, 29, 36, and 43 during radiation therapy. | 9 | None | 81 | 134 | 96 | 134 | View |
