中文摘要:
      笔者提出标准化预告值(SPV)新概念及相应标化方法。本文将不受患病率或样本构成影响,而是在一个指定的标准构成条件下获得的理论预告值定义为标准化预告值,它只随试验的灵敏度和特异度的变化而变化。标准化预告值的意义在于用统一标准去解释、判断和衡量诊断试验的诊断价值。
英文摘要:
      A new concept and method of standardizing predictive value was put forward. The theoretical predictive value which was not affected by prevalence rate or different component in normal and abnormal groups and was gotten under the appointed standardizing condition that made the cases in the two groups to be same with each other and to be called standardizing component was defined as standardizing predictive value, The value will change only with the change of sensitivity and specificity of diagnostic test. By the new concept and method, the value of diagnostic test can be explained, judged and expressed in unique standard.
