• Researchers and sponsors should make provisions for post-trial access for participants who need beneficial interventions
• There is no obligation to provide post-trial access
• Post-trial access is the sole responsibility of national health systems, not researchers

• When clinicians provide therapy instead of enrolling patients in research
• When a therapy is proven effective in both research and clinical care
• When a placebo is thought to be an active drug

Correct Answer: When research participants mistakenly believe the primary purpose of a clinical trial is to provide individualized therapeutic benefit rather than to generate generalizable knowledge
