Which statement best captures a feature of the Declaration of Helsinki?

• A. It provides guidelines for international medical research and includes independent ethical review.
• B. It requires that editors for journals ensure published research conforms to Helsinki.
• C. It bans placebo controls in all trials.
• D. It eliminates informed consent requirements for low-risk studies.

Answer: (A)

At its core, the Declaration of Helsinki sets international ethical principles for medical research involving human subjects, guiding how studies should be designed and conducted to protect participants. A defining feature is the requirement that research be reviewed by an independent ethics committee or Institutional Review Board, ensuring that risks are minimized, potential benefits justify any risks, and participants’ rights are safeguarded. It also emphasizes obtaining voluntary informed consent and applying ethical standards across research conducted anywhere in the world, not tied to a single publication venue or editorial gatekeeping.

That makes the statement about providing guidelines for international medical research and including independent ethical review the best fit. Placebo controls are not banned in all cases—they’re allowed under circumstances where no proven effective treatment exists or when adding to standard therapy—so that option isn’t accurate. The Declaration does not eliminate informed consent; it underscored consent as essential, with only specific, limited waivers in extraordinary situations. And while journals may require compliance with ethical guidelines for publication, the Declaration itself centers on ethical review and participant protection, not editorial enforcement alone.
