The Community Guide conducts systematic reviews of interventions in several subject areas to find out what functions to promote general health. The Community Preventive Services Task Force (CPSTF) utilizes the outcomes of those reviews to issue holistically findings and recommendations into the public wellbeing. A systematic review is a summary of research on a particular topic. Each review is conducted by specialists in subject matter experts and systematic inspection procedures. The Community Guide, with advice from the CPSTF, conducts every review using measures. The evaluation of research provides adequate or strong evidence that the intervention is not effective or harmful.
