Table 3.

Spearman’s correlation coefficients for three methods of mycobacteria detection.

Detection Method	ZN Microscopy	Culture Examination	qPCR
ZN microscopy		0.4298	0.5809
Culture examination	0.4298		0.6139
qPCR	0.5809	0.6139

Table interpretation. ZN = microscopy examination after the Ziehl-Neelsen staining in at least 200 fields [43]; qPCR = quantitative PCR test.
