14、ons After May 2007-5,Grade I Statement The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of the service. Evidence is lacking, of poor quality, or conflicting, and

15、 the balance of benefits and harms cannot be determined.Read the clinical considerations section of USPSTF Recommendation Statement. If the service is offered, patients should understand the uncertainty about the balanc

16、e of benefits and harms.,Levels of Certainty Regarding Net Benefit-1,High：The available evidence usually includes consistent results from well-designed, well-conducted studies in representative primary care populations.

17、 These studies assess the effects of the preventive service on health outcomes. This conclusion is therefore unlikely to be strongly affected by the results of future studies.,Levels of Certainty Regarding Net Benefit-2

18、,Moderate：The available evidence is sufficient to determine the effects of the preventive service on health outcomes, but confidence in the estimate is constrained by such factors as: The number, size, or quality of ind

19、ividual studies. Inconsistency of findings across individual studies. Limited generalizability of findings to routine primary care practice. Lack of coherence in the chain of evidence. As more information becomes availab

20、le, the magnitude or direction of the observed effect could change, and this change may be large enough to alter the conclusion.,Levels of Certainty Regarding Net Benefit-3,Low：The available evidence is insufficient to

21、assess effects on health outcomes. Evidence is insufficient because of: The limited number or size of studies. Important flaws in study design or methods. Inconsistency of findings across individual studies. Gaps in

22、the chain of evidence. Findings not generalizable to routine primary care practice. Lack of information on important health outcomes. More information may allow estimation of effects on health outcomes.,Grade Definiti

31、 health outcomes, but the strength of the evidence is limited by the number, quality, or consistency of the individual studies, generalizability to routine practice, or indirect nature of the evidence on health outcomes.

32、,Quality of Evidence-3,Poor: Evidence is insufficient to assess the effects on health outcomes because of limited number or power of studies, important flaws in their design or conduct, gaps in the chain of evidence, or
