^*HAART contained at least one protease inhibitor and/or one non-nucleoside reverse transcriptase inhibitor and two reverse transcriptase inhibitors of HIV-1. 

^† Measured by ultrasensitive bDNA assay with a detection limit of 50 copies per ml plasma. 

^‡ Coreceptor usage of isolated virus was evaluated on U87.CD4 cells expressing the chemokine receptors CCR5 or CXCR4. 

^§ Determined by measuring INF-γ-positive cells on stimulation with overlapping 20-mer Gag peptides.
