Comparison of the Diagnostic Efficiency of Pathology, Molecular Tests, and Parallel Test Using Different Specimen Types for the Diagnosis of Lymph Node Tuberculosis

Test	Sensitivity (P-value)	Specificity (P-value)	PPV (P-value)	NPV (P-value)	AUC (P-value)
Pathology (Tissue vs CNB)	0.280	0.529	0.458	0.609	0.188
Molecular test (Tissue vs CNB)	0.111	1.000	1.000	0.136	0.346
Parallel test (Tissue vs CNB)	0.089	0.529	0.472	0.062	0.843

Abbreviations: PPV, positive predictive value; NPV, negative predictive value; AUC, area under the curve; CNB, core needle biopsy.
