- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- Baseline (pre-treatment)
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- Month 2 and Month 5 follow-up
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Sputum collected at 2 months (end of intensive phase) and 5 months (end of therapy) of first-line anti-TB regimen.
- Group 0 sample size Number of subjects in the control (unexposed) group
- 106
- Group 1 sample size Number of subjects in the case (exposed) group
- 44
- Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
- All were treatment-naïve at baseline; no anti-TB drugs prior to sampling; other antibiotic history not exclusionary.
Lab analysis
- Sequencing type

Statistical Analysis
- Data transformation Data transformation applied to microbial abundance measurements prior to differential abundance testing (if any).
- relative abundances
- Statistical test
- ANOVA
- Kruskall-Wallis
- Mixed-Effects Regression

- MHT correction Have statistical tests be corrected for multiple hypothesis testing (MHT)?
- Yes
- Confounders controlled for Confounding factors that have been accounted for by stratification or model adjustment
- Confounders controlled for: "HIV status" is not in the list (abnormal glucose tolerance, acetaldehyde, acute graft vs. host disease, acute lymphoblastic leukemia, acute myeloid leukemia, adenoma, age, AIDS, alcohol consumption measurement, alcohol drinking, ...) of allowed values.HIV status, Confounders controlled for: "BMI" is not in the list (abnormal glucose tolerance, acetaldehyde, acute graft vs. host disease, acute lymphoblastic leukemia, acute myeloid leukemia, adenoma, age, AIDS, alcohol consumption measurement, alcohol drinking, ...) of allowed values.BMI, Confounders controlled for: "gender" is not in the list (abnormal glucose tolerance, acetaldehyde, acute graft vs. host disease, acute lymphoblastic leukemia, acute myeloid leukemia, adenoma, age, AIDS, alcohol consumption measurement, alcohol drinking, ...) of allowed values.gender
