The phylum fractions in bronchial washing (a and b) and PSB (c and d) samples from the NTM-PD and control groups. The volcano plots show the relative fold changes and whether they were significant. Differences were assessed using Student’s t-test; the p-values of all phylum fractions in the NTM-PD compared with the control group are shown (a, c). Red indicates statistical significance (p < 0.05) after adjustment for BMI (by ANCOVA). NTM-PD, non-tuberculous mycobacterial pulmonary disease; PSB, protected specimen brushing; BMI, body mass index
