What edition-related information is suggested to be provided?

• A. The edition's release date
• B. The sponsor's annual report
• C. The edition number and the reference to the edition it supersedes
• D. The list of investigators

Answer: (C)

Tracking which document version you follow is essential because guideline updates can change how consent, reporting, and oversight are handled. Providing the edition number along with the edition it supersedes offers a precise reference to the exact requirements in force for the trial and shows the evolution from the previous edition. The release date alone may identify a version but doesn’t convey its relationship to earlier editions or what changed. A sponsor’s annual report or the list of investigators doesn’t inform which edition of a guideline or document applies, so they’re not appropriate for this purpose.
