Level of EvidenceN/A
The strength of the evidence to answer any clinical question depends on the quantity and quality of the evidence and the consistency of findings across studies. The nature of the clinical question determines what study designs provide the strongest evidence. Randomized clinical trials provide the strongest evidence for therapy and harm questions, while various descriptive study designs provide strongest evidence for prognosis, diagnosis and human response / meaning questions. A systematic review of individual studies is a particularly efficient way for practitioners to determine the quantity of evidence as well as the consistency of findings. For evidence-based practice guidelines, explicit scales rate the strength of evidence underlying recommendations.
