Adjusted hazard ratios for mortality at 12 weeks (baseline variables).

<p>There is little evidence that the association between phosphate and the hazard of death is non-linear based on a likelihood ratio test (p = 0.27). Similarly, there is little evidence that the association between any continuous variable and the hazard of death is non-linear (p>0.20 for each).</p

Baseline participant characteristics.

<p>Abbreviations: ART, antiretroviral therapy; BMI, body mass index; BUN, blood urea nitrogen; hsCRP, high sensitivity C-reactive protein; IQR, interquartile range.</p><p>Among the 142 cases included in the multivariable analysis, values were missing for the following measurements: 8 (6%) baseline serum phosphate, 31 (22%) week one serum phosphate, 29 (20%) baseline hemoglobin (because either blood or assay reagents could not be obtained), 2 age (birth dates unknown), and one BMI (participant could not stand for height measurement).</p><p>*Normal creatinine range: females 44–80, males 53–106 µmol/L; normal albumin range: females 41–53, males 40–50 g/L; normal ferritin range: females 10–150, males 29–248 µg/L.</p
