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

|---|---|---|---|---|---|---|---|---|
| Ribavirin Dose Reduction Arm | After the initiation of treatment with 4 weeks with PEG2b/RBV followed by 24 or 44 weeks of boceprevir, participants who became anemic (serum hemoglobin = ≤10 g/dL) within the 28- or 48-week treatment period and who were randomized to the Ribavirin (RBV) Dose Reduction Arm received reduced doses of RBV for management of the anemia in combination with PEG2b and boceprevir therapies. | None | None | 39 | 249 | 247 | 249 | View |
| Erythropoietin Use Arm | After the initiation of treatment with 4 weeks with PEG2b/RBV followed by 24 or 44 weeks of boceprevir, participants who became anemic (serum hemoglobin = ≤10 g/dL) within the 28- or 48-week treatment period and who were randomized to the Erythropoietin Use Arm received erythropoietin for management of the anemia in addition to PEG2b/RBV and boceprevir therapies. | None | None | 33 | 251 | 248 | 251 | View |
| Treated/Not Randomized | Participants received 4 weeks of PEG2b/RBV followed by 24 or 44 weeks of boceprevir plus PEG2b/RBV depending on Hepatitis C Virus RNA (HCV-RNA) levels. Participants continued with this treatment if their serum hemoglobin remained \>10 g/dL throughout the 28- or 48-week treatment period. | None | None | 15 | 187 | 180 | 187 | View |
