Large-Scale Evidence-Based Guideline Development Engaging the International PCOS Community.

The evidence-based guideline for the assessment and management of polycystic ovary syndrome (PCOS) integrates the best available evidence with international, multidisciplinary clinical expertise and consumer preferences to provide health professionals, consumers, and policy makers with high-quality, comprehensive guidance about diagnosing and managing PCOS. Here, we outline the rigorous and systematic process, defined a priori and documented to be reproducible, to minimize bias and maintain transparency, in alignment with the Appraisal of Guidelines for Research and Evaluation (AGREE II) criteria and incorporating the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework that render this PCOS evidence-based guideline credible, trustworthy, reliable, and useable.
