Study limitation reported by the research below: “The DOI and journal metadata indicate this is published as an IUGA guideline in 2026, but the full text content is an RCOG Consent Advice No. 9 document dated June 2010 — there is a significant mismatch between the cited publication metadata and the actual document content. Risk figures and referenced guidelines (e.g., Green-top Guideline No. 29, 2007) may be outdated relative to the 2026 publication date.”
