Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Microbial diversity and composition measured using richness, Pilous evenness, Berger-Parker dominance, Shannon and Simpson indices to explore alpha diversity and Jaccard, Bray-Curtis and Unifrac measures to explore beta diversity, at before and after anti tuberculosis treatment (the standard duration of anti-tuberculosis treatment is 6 months; however, treatment may be extended to 9 or 12 months if response to treatment is considered unsatisfactory) | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Clinical responses measured using demographics, symptom burden, health-related quality of life (measured using EQ-5D-5L questionnaire), and lung function test with spirometry 2. Microbiological responses measured using smear status, Xpert grade, time to positive culture, molecular and phenotypic drug sensitivity 3. Radiological responses: CXR and CT to determine % lung involvement and evidence of extrapulmonary disease 4. Physiological and metabolic responses measured using physical activity monitoring (PAM), muscle function assessments (MFAs) with handgrip strength and quadriceps strength tests, muscle biopsy, body composition measurements with dual energy x-ray absorptiometry (DEXA) scan and bioelectrical impedance analysis (BIA) Measured at 2 weeks, 8 weeks, 16 weeks and 24 weeks after the anti-tuberculosis treatment start date and end of treatment. Participation at 6 months and 12 months after the treatment end date is optional. | — |
