Adverse Events Module

Adverse Events Module

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

NCT ID: NCT01300234
Description: Serious adverse events (SAEs) and non-serious AEs were collected in members of the Safety Analysis (SA) Population, comprised of all participants who received at least one dose of study medication and had at least one post-Baseline safety assessment.
Frequency Threshold: 0
Time Frame: Serious adverse events (SAEs) and non-serious adverse events (AEs) were collected from the start of the study treatment up to 240 weeks treatment period and 24 weeks follow-up visit off treatment.
Study: NCT01300234
Study Brief: Efficacy and Safety of Tenofovir Disoproxil Fumarate (TDF) 300mg in Chinese Subjects With Chronic Hepatitis B (CHB)
