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

| Nirmatrelvir + Ritonavir 5 Day Then Placebo 10 Day | Eligible participants were randomized to receive nirmatrelvir 300 milligram (mg) and ritonavir 100 mg orally every 12 hours (q12h) for 5 days. Participants with estimated glomerular filtration rate (eGFR) \>=30 to less than (\<) 60 milliliters per minute (mL/min)/1.73 square meter (m\^2) or estimated creatinine clearance (eCrCl) \>=30 to \<60 mL/min received nirmatrelvir 150 mg and ritonavir 100 mg orally q12h for 5 days. Participants then received placebo for nirmatrelvir and placebo for ritonavir q12h for next 10 days. Participants had follow-up through Day 44. Participants had long term follow-up through Week 24. | 1 | None | 5 | 54 | 12 | 54 | View |
