Reporting guidelines can also be used for critical appraisal.
Professional groups, non-profit organizations, and government agencies often develop guidelines and make them available freely on their websites. Search or browse groups like the World Health Organization, U.S. Centers for Disease Control and Prevention, U.S. Veterans Health Administration, or U.S. Preventive Services Task Force. Use Google to find additional groups focused on your specialty.
National Guideline Clearinghouse ceased in July 2018. There is no replacement product with the scope and depth of NGC. Use one or more of these sources to identify and access full-text guidelines.
