^aAdjusted models comparing participants treated for tuberculosis disease to those participants in the untreated control group controlled for age at baseline and sex. Adjusted models comparing participants treated for latent tuberculosis infection to those participants in the untreated control group controlled for age at baseline and sex.
^bControl is a participant screened for tuberculosis who tested negative for tuberculosis and was found not to require treatment.
*Indicates a p-value less than 0.05 meaning a statistically significant difference in mean mental component summary scores reported by the group of treated participants and the participants in the control group in the adjusted model, at the given visit.
