Table 2. Diagnostic performance of DNA microarray for INH resistance.

Detection method	Results	Traditional liquid culture		Se	Spe	AUC (95% CI)	P	Difference value (95% CI, %)	P	Kappa (95% CI)
Detection method	Results	Sensitive	Resistant	Se	Spe	AUC (95% CI)	P	Difference value (95% CI, %)	P	Kappa (95% CI)
DNA microarray	Sensitive	559	66	0.73	0.97	0.85 (0.82–0.87)	<0.001	6.06 (3.95–8.17)	<0.001	0.75 (0.70–0.80)
DNA microarray	Resistant	16	184	0.73	0.97	0.85 (0.82–0.87)	<0.001	6.06 (3.95–8.17)	<0.001	0.75 (0.70–0.80)

AUC, area under the curve; CI, confidential interval; INH, isoniazid; Se, sensitivity; Spe, specificity.
