Where should trial registration occur to support transparency?

• A. Publicly accessible databases.
• B. Internal company records only.
• C. Personal emails of investigators.
• D. Printed newsletters only.

Answer: (A)

Registering a trial in publicly accessible databases ensures transparency by creating an open, time-stamped record that details the study design, planned outcomes, interventions, eligibility criteria, and analysis plan. This makes information available to researchers, clinicians, regulators, and the public, allowing independent verification, preventing selective reporting, and enabling others to see how the study was intended to be conducted and analyzed before results are known. Public databases also support consistency and searchability, so the trial can be identified, compared, and linked to results across sources.

Internal company records, personal emails, or printed newsletters don’t offer that level of openness or verifiability. They stay private, are harder to discover or audit, and can be incomplete or inaccessible to external stakeholders, which undermines accountability and the ability to assess potential biases or duplications.
