Overall, 223 HIV-infected adults initiating ART were enrolled in the Uganda AIDS Rural Treatment Outcomes (UARTO) cohort from May 2007 and April 2009, all of whom had stored baseline serum available for this analysis. We excluded two patients missing baseline symptom data, five patients receiving TB treatment at the time of study enrollment, and 15 patients with unknown six-month TB status (six withdrew study consent, two were lost to follow-up [LTFU] and seven died). Thus, 201 patients were included in this analysis.
