Comparative analysis of 100 Pleural fluid samples with N-PCR, Culture and AFB with clinical diagnosis.

NOTE. Clinical diagnosis, Categorization of patients and controls as describe in methods; PPV, positive predictive value; NPV, negative predictive value; Sensitivity, TP/(TP+ FN) x 100, where T is true, F is false, P is positive, and N is negative; Specificity, TN/(TN+ FP) x 100; N-PCR, 116 bp amplicon generated by Nested-PCR assay specific for Mycobacterium tuberculosis; Culture, AFB Growth detected on LJ, 7H9 and/MGIT; AFB, acid fast bacilli.

注：临床诊断、如方法部分所述的患者与对照分组；PPV（阳性预测值，positive predictive value）；NPV（阴性预测值，negative predictive value）；灵敏度：TP/(TP+FN)×100，其中T表示真、F表示假、P表示阳性、N表示阴性；特异度：TN/(TN+FP)×100；N-PCR：针对结核分枝杆菌（Mycobacterium tuberculosis）的巢式PCR（Nested-PCR）检测所获得的116 bp扩增片段；培养法：在LJ、7H9及MGIT培养基中检测到的AFB（抗酸杆菌，acid fast bacilli）生长；AFB即抗酸杆菌（acid fast bacilli）。
