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 |
|---|---|---|---|---|---|---|---|---|
| Valganciclovir 900 mg BID | Participants received 900 mg of valganciclovir along with a placebo matched to maribavir, BID orally for 8 weeks. Valganciclovir dose was allowed to be adjusted to 450 mg BID or 450 mg QD based on renal function impairment assessed at baseline or development of neutropenia during the study. | 29 | None | 95 | 274 | 256 | 274 | View |
