摘要
目的介绍信息熵在诊断试验评价meta分析中的应用。方法信息熵结合meta分析对IHC、MHI两种方法诊断HNPCC进行评价,与诊断试验meta分析SROC方法的结果进行对比。结果信息熵方法得到的结论与经典的SROC方法的结论一致,反映的信息量更大,是对经典SROC方法的有益补充。结论信息熵可以作为一种新的诊断试验评价meta分析的指标。
Objective:Introduction of entropy method in meta analysis of diagnostic test evaluation.Methods:Entropy method was performed in meta analysis of evaluating IHC and MHI,which were used to diagnose HNPCC,and compare the meta analysis results of entropy method and SROC method.Results:The conclusion of entropy method was consistent with the result of classical SROC method,reflecting a greater amount of information.Conclusion:Entropy method is a complement to the classic SROC method adn can be used as a new diagnostic test evaluation index of meta analysis.
