Quantification of 2-LTR circles in blood samples.

aDetermined subtracting the level of 2-LTR from all unintegrated HIV DNA forms, taking into account the similar PCR efficiencies of 2-LTR and UF. bThe median (IQR) value for 2-LTR/µg DNA was 2 (<2–5) and <2 (<2–4) for MDR and non-MDR group, respectively; for 2-LTR/104 CD4+ was 4 (1–7) and 2 (1–3) for the MDR and non-MDR group, respectively. The median (IQR) value for UF HIV DNA/µg DNA was 3 (<2–5) and 7 (3–11) for the MDR and non-MDR groups, respectively; for UF HIV DNA/104 CD4+ was 6 (1–9) and 5 (2–10) for the MDR and non-MDR group, respectively. The median (IQR) value for 1-LTR + linear forms/µg DNA was 0 (0–2) and 3 (1–8) for the MDR and non-MDR group, respectively; for 1-LTR + linear forms/104 CD4+ was 0 (0–1) and 2 (1–7) for the MDR and non-MDR group, respectively.
