1. SD – standard deviation; CI – confidence interval
2. 1 CD4 count, plasma HIV-1 RNA, serum albumin were modeled as continuous variables, and the acute phase response was modeled as a dichotomous variable.
3. 2 Calculated by using t-tests for continuous variables and χ2 tests for dichotomous variables.
4. 3 Odds ratio is per 100 CD4 cells/μl increase.
5. 4 The presence of C-reactive protein ≥ 1 mg/dl and/or α1-acid glycoprotein ≥ 100 mg/dl.
6. 5 Defined as fever for ≥ 1 month, diarrhea for ≥ 1 month, cough for ≥ 1 month, unintended weight loss of ≥ 5 kg during previous year, or itching skin rash during previous year.
7. 6 Defined as the presence of oral thrush, oral hairy leukoplakia, oral ulcer, maculopapular rash, or Kaposi's sarcoma.
