脾虚证计量诊断的前瞻性研究

A Prospective Study of Quantitative Diagnosis for Spleen-Deficiency Syndrome: Evaluation for Diagnostic Accuracy in 549 Cases

以本研究所修订的“脾虚证诊断标准”为金标准，通过以整群抽样取得的５４９例各科各系统病人（包括脾虚２２９例，非脾虚３２０例）的四诊资料对笔者以往建立的“脾虚证诊断计分表”的诊断效果做了前瞻性的研究。该计分表诊断脾虚证的几项主要评价指标的结果为：患病率４１．７％，准确度９１．３％，敏感度９３．０％，特异度９０．０％，阳性预测值８６．９％，阴性预测值９４．７％，阳性拟然比９．３０，阴性拟然比０．０８，诊断效果满意。

Aprospective study had been carried out for the diagnostic accuracyof D1AGNOST1C SCORETABLE OF SPLLEN-DEF1C1ENCY SYNDROME(DSTSDS) which was established by the author before.Bycluster sampling,the data of four methods of examination in 549 cases(229 cases with spleen-deficiency syndrome and 320 cases without spleen-deficiency syndrome) werecollected. The diagnos tic criteria for spleen-deficiency syndrome eStablishedby our institute was used as the gold standad. The evaluation criteriacalculated from DSTSDS were as follows: prevalence 41.7%, accuracy 91.3%,sensitivity 93.0%, specificity 90.0%, positive predictive value 86.9%, negativepredictive value 94.7%, positive likelihood ratio 9.30 and negative likeli-hoodratio 0.08.
