1. Real-World Evidence: These studies reflect actual clinical practice and patient behavior, providing evidence that is often more generalizable than that obtained from controlled trials. 2. Ethical Considerations: They are particularly useful in situations where it would be unethical to withhold treatment or expose participants to potential harm. 3. Longitudinal Data: Cohort studies, in particular, can provide valuable longitudinal data, helping to understand how diseases develop and progress over time.
