Task: Answer Verification
Input (English): Question: Is use of biomass fuel in households a risk factor for pulmonary tuberculosis in South Ethiopia?
Answer: We found no evidence of an association between the use of biomass fuel and TB. Low statistical power due to the selection of neighbourhood controls might have contributed to this negative finding. We would advise that future protocols should not use neighbourhood controls and that they should include measurements of indoor air pollution and of exposure duration.
Output (English): no
