| 中文摘要: |
| 目的介绍诊断试验评价的Meta分析方法。方法以7篇B超诊断脂肪肝的研究为例,运用调整SROC法对其进行综合评价。结果用调整SROC法求得B超的灵敏度为0.89(95%CI0.87～0.92),特异度为0.94(95%CI0.92～0.96),Q值为0.90。结果表明,B超的诊断价值较高,可作为脂肪肝诊断的有效方法。结论运用诊断试验评价的Meta分析方法,可对诊断试验的诊断价值做出综合评价,增加研究结论的统计功效,提高结论的可靠性。 |

| Objective To introduce Meta-analysis in evaluating diagnostic tests.Method Adjusted SROC method was used in assessing 7 diagnostic tests on fatty liver.Results The pooled sensitivity and specificity of type B ultrasonography were 0.89 [95% confidence interval(CI): 0.87- 0.92 ] and 0.94 (95%CI: 0.92- 0.96 ) respectively while the Q value was 0.90 by adjusted SROC method.The results indicated that the diagnostic value of type B ultrasonography were high,thus could be regarded as an effective method for fatty liver diagnosis.Conclusion Meta-analysis on evaluating diagnostic tests could be used to assess the diagnostic test to increase the power of conclusion,and to improveits its reliability. |
