  1. 18F-FDG PET/CT: 18F-fluorodeoxyglucose positron emission tomography/computed tomography; NTM: Non-tuberculous mycobacterial infection; NTM-PD: Non-tuberculous mycobacterial pulmonary diseases; SUVTop: The most FDG-avid lesion in the whole body; SUVI−lung: SUVmax of lung lesions, SUVE−lung: SUVmax of extra-lung lesions; SUVLiver: SUVmax of liver; SUVSpleen: SUVmax of spleen; SUVMarrow: SUVmax of marrow; SURLiver: SUVmax ratio of lesion-to-liver; SURBlood: SUVmax ratio of lesion-to-blood pool. MLV: the metabolic lesion volume; TLG: total lesion glycolysis
  2. NA#: Localized groups were defined as NTM patients with only pulmonary involvement
  3. *: P value less than 0.05 was considered statistically significant
