What is the primary purpose of establishing the 'Document History' section in a guideline?

• A. To describe the financial sponsor history of the guideline.
• B. To provide a timeline of the guideline's development and revisions.
• C. To list all organizations involved in drafting the guideline.
• D. To explain how to cite the guideline in manuscripts.

Answer: (B)

Document History records when the guideline was created and each update, including dates, versions, what changes were made, and who approved them. This enables traceability and ensures readers and auditors can see how the document has evolved, confirm they’re using the most current version, and understand the rationale behind edits. The other options don’t fit because sponsor history concerns funding rather than document control, listing organizations relates to authorship or governance rather than change tracking, and citing guidance belongs in how to reference the document, not in the change log.
