| | | Patients with tuberculosis () | Patients with latent Mycobacterium tuberculosis infection () | Healthy controls () |
| | Age in years (median (range)) | 14.7 (5.8 to 37) | 14.7 (4.5 to 49) | 24 (9 to 40) |
| | Gender (female) | 7 | 19 | 6 |
| | Manifestations of disease | 9 pulmonary tuberculosis, 3 extrapulmonary tuberculosis (1 each lymphadenitis, mandibular, and peritoneal) | No disease manifestations | No disease manifestations |
| | Isolation of Mycobacterium tuberculosis | 6/9 patients with pulmonary tuberculosis, and one each with tuberculous lymphadenitis, and mandibular tuberculosis | N/A | N/A |
