Truenat	Culture		Total	Xpert	Culture		Total
	Positive	Negative			Positive	Negative
Positive	183	376	559	Positive	148	160	308
Negative	61	1226	1287	Negative	96	1442	1538
Total	244	1602	1846	Total	244	1602	1846
Sensitivity: 75% (69.1-80.3%)				Sensitivity: 60.7% (54.2-66.8%)
Specificity: 76.5% (74.4-78.6%)				Specificity: 90.0% (88.4-91.4%)

Sensitivity of Truenat and Xpert in detecting MTB among smear-negative samples in comparison with culture was 75 and 60.7% while specificities were 76.5 and 90.0%, respectively. The differences in sensitivity and specificity between Truenat and Xpert were significant (P<0.001)
