Table 4. . Agreement between the results of 16S rRNA sequencing, ITS sequencing and MALDI-TOF.

Tests compared (Total tests, n = 90)	Statistical agreement	95% CI
Concordance of 16S rRNA sequencing and MALDI-TOF   • Rapidly growing NTM   • Slowly growing NTM	83% (cumulative) 94.5% 77.5%	74.00–90.4% 81.3–99.4% 63.9–81.4%
Concordance of ITS sequencing for slowly growing NTM and MALDI-TOF	76%	63.9–81.4%

ITS: Internal transcribed spacer; MALDI-TOF: Matrix assisted laser desorption ionization-time of flight; NTM: Non-tuberculous mycobacteria.
