In the multivariable backward stepwise logistic regression model retaining the variables that improved the Akaike information criterion, the odds were lower for the duration of therapy (OR: 0.96; p = 0.0397), prescriber’s perception of adherence to therapy (OR: 0.50; p < 0.0001), and Nadir CD4+ T-cell count (OR: 0.85; p = 0.0329), and higher for the presence of AIDS (OR: 1.89; p= 0.0423) and COVID-19 (OR: 2.31; p = 0.0182). This evidence concerns the gene CD4 and AIDS.
