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 |
|---|---|---|---|---|---|---|---|---|
| High Tranfusion Threshold | Transfusions were administered using a higher threshold hemoglobin value. AKA "Liberal Cell Transfusion" group. | 146 | None | 206 | 908 | 184 | 908 | View |
| Low Transfusion Threshold | Transfusions were administered using a lower threshold hemoglobin value. The low threshold values reflect more common practice, so this is considered the 'usual treatment' group. AKA "Restricted Red Cell Transfusion" group. | 135 | None | 197 | 906 | 164 | 906 | View |
