There were no seroconversions during the study. One subject confirmed to be HIV-1+ by antibody test at entry subsequently tested seronegative as well as negative by PCR. Loss of HIV-1 antibody together with a negative PCR result have been demonstrated previously (16) and may be more common than formerly thought (41). Hence, this subject was retained as seropositive; eliminating him from the sample did not affect the results reported herein.
Only age and health insurance were significantly different by HIV-1 serostatus (P ≤ 0.05). Education showed a nonsignificant trend toward a difference (P ≤ 0.07). These variables were not significantly different by treatment assignment and were not considered control variables.
Standard deviations appear in parentheses.
Means for income last month were based on nHIV-1− = 41 and nHIV-1+ = 69.
The percentages for health insurance data were based on nHIV-1− = 44 and on the full subsample (n = 74) of HIV-1+ subjects.
The percentages for annual income data were based on nHIV-1− = 44 and nHIV-1+ = 73.
The percentages for living arrangement data were based on nHIV-1− = 45 and nHIV-1+ = 72.
