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 that cover all health topics and areas 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 area or a specific condition.
