| Abstract: |
| 目的 探讨证据分级评价系统在临床决策分析中应用的可行性。方法 该系统定性分级以及界值点NNTT的估计过程,结合具体实例,进行临床决策分析。结果 该例NNTT为12,与不治疗的效应量NNT=6相比,NNT<NNTT,表明利大于弊。结论 证据分级评价系统应用过程中,正确获取不良事件的发生率以及货币化,十分关键。 |

| Objective To explore feasibility of applying evidence grading system in clinical decision- making analysis. Methods Using grading system as well as a quantitative approach to generate the threshold NNT_(T), and conducting clinical decision-making analysis through one study on Asymptomatic carotid atherosclerosis. Results NNT_(T) was 12, comparing with no-intervention in the ACA study that NNT=6. NNTNNT_(T) indicated the benefits of intervention outweigh the risks and costs. Conclusion To obtain the rate of adverse event and the specifying approximate cost were vital in the process of appklying grading system in clinical decision-making. |
