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 |
|---|---|---|---|---|---|---|---|---|
| Treatment Arm | Participants in the treatment group received darbepoetin alfa subcutaneously (SC) at a dose of 3.0 μg/kg once every 2 weeks for 21 weeks. The dose of darbepoetin alfa could be increased at week 7 (to 5.0 μg/kg once every 2 weeks) or at week 13 (to 9.0 μg/kg once every 2 weeks) in participants with a hemoglobin change from baseline of less than 1.0 g/dL who dose escalated at week 7. | None | None | 65 | 226 | 99 | 226 | View |
| Observation Arm Treated | Participants in the observation group who received darbepoetin alfa, initiated at a dose of 3.0 μg/kg once every 2 weeks beginning with the first visit after the test period at which the participants hemoglobin concentration was less than or equal to 11.0 g/dL. The dose of darbepoetin alfa could be increased to 5.0 μg/kg once every 2 weeks after 6 weeks of darbepoetin alfa treatment in participants with a hemoglobin change from baseline of less than 1.0 g/dL. Adverse events for participants in this group could have been reported at any time during the study; and therefore, may have occurred before darbepoetin alfa administration. | None | None | 4 | 33 | 21 | 33 | View |
| Observation Arm Not Treated | Participants in the observation group who did not receive any darbepoetin alfa treatment. | None | None | 4 | 26 | 6 | 26 | View |
