Detailed Explanation
Causality assessment represents a critical analytical process in pharmacovigilance, requiring investigators and sponsors to evaluate whether observed adverse events are attributable to the investigational product, underlying disease, concomitant medications, or other factors. This determination influences regulatory reporting obligations, risk-benefit evaluations, and ultimately the decisions made about product development and labeling. While establishing definitive causality is often impossible, standardized approaches enable consistent and defensible assessments.
