NOTE. The model included all variables with P < .10 on univariate analysis (table 1), and only variables with P < .05 (in boldface) are displayed. Age, lamivudine use, CD4 cell count, and alanine aminotransferase level were also included in the model. Ab, antibody; aOR, adjusted odds ratio; CI, confidence interval.
