The Agency for Healthcare Research and Quality (AHRQ)reviewed 40 systems used to evaluate the quality of studies and strength of evidence.The report identified three domains for evaluating systems that grade the strength of evidence: quality,quantity,and consistency.The quality of a study refers to the extent to which bias is minimized.Quantity refers to the number of studies,the magnitude of the effect,and the sample size.Consistency refers to studies that have similar findings,using similar and different study designs.Federally supported multiagency clinical studies,research studies completed by multidisciplinary teams in multiple settings,and controlled clinical trials do not necessarily meet the three domains for evaluating systems to grade the strength of the evidence: quality,quantity,and consistency.These are the criteria that should be used to evaluate the literature so additional information is needed about these studies in order to evaluate them.
