Table 3. Comparison of NAAT test with rapid diagnostic test.

	RDT
NAAT	Positive	Negative	Total
Positive	0	1	1
Negative	71	712	783
Total	71	713	784
Cohen’s Kappa = −0.0025
Kendall’s Tau B = −0.0113

Cohen’s Kappa, which tests the agreement between two tests is negative, showing no agreement. Kendall’s Tau B is also negative, showing very slight negative association (inversion) between the two tests. The association here is very limited.

The prevalence detected using the NAAT (considered the gold standard for this study) was 0.1% (95% CI: 0–0.38%).
