Stakeholder Reactions And Criticism: Pro-life groups condemned the extended timeline as a delay and demanded immediate action, while reproductive-rights advocates called the review politically motivated and defended mifepristone as safe and effective. The status report prompted public statements from both sides criticizing the pace, scope and transparency of the review.

Study Design And Methods: The agency said it is using a statistical data-mining method (TreeScan) on Sentinel’s electronic medical database and will compare outcomes for roughly 100,000 women who took mifepristone with a comparator group who underwent surgical abortions through 10 weeks’ gestation. The filing described this approach as a way to detect unknown safety concerns.
