Factors associated with HIV-1 RNA >50 copies/ml at visit 2.

<p>Odds ratios from uni- and multivariable logistic regressions are shown with 95% confidence intervals. Panel A includes patients who initiated ART the mono/dual era, and panel B those who initiated ART in the cART era. Multivariable models were also adjusted for age, sex, transmission risk group, HCV co-infection, total duration of ART therapy, maximum viral load ever and CD4 cell count at the first visit in 2007 (all p-values >0.05).
