Abstract

To explore feasibility of applying evidence grading system in clinical decision-making analysis. 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. NNT((T)) was 12, comparing with no-intervention in the ACA study that NNT = 6. NNT < NNT((T)) indicated the benefits of intervention outweigh the risks and costs. To obtain the rate of adverse event and the specifying approximate cost were vital in the process of applying grading system in clinical decision-making.
