|Table 2: Pre-treatment serum phosphate and odds ratios of death prior to 12 weeks among study participants, stratified by BMI ()*.|
|Two patients with known vital status at 90 days (one alive and one deceased) were missing baseline BMI and excluded from the analysis.|
**Adjusted for sex, age, and lymphocyte count at ART initiation.
The effect of lower serum phosphate on the odds ratio of mortality remained significant for participants with BMI <18.5 kg/m2 when the model was further adjusted for pretreatment serum hsCRP, ferritin, and albumin levels (OR 1.22, 95% CI: 1.01 to 1.48; ). When adjusted for concomitant tuberculosis treatment the odds ratio of mortality also remained significant for participants with BMI <18.5 kg/m2 (OR 1.27, 95% CI: 1.06 to 1.51; ).
