JAMAevidenceEvidence-based medicine (EBM) integrates the best available evidence with clinical experience that allows clinicians to recommend, and their patients to make, informed choices consistent with their values. JAMAevidence helps decision makers identify the best available evidence by providing guides to the systematic consideration of the validity, importance, and applicability of claims about the assessment of health problems and the outcomes of health care.
