Table 1 HIV-1 antibody measurements in HIV-1 infected patients with ≥ five-years undetectable viral load

From: Absence of seroreversion in 80 HAART-treated HIV-1 seropositive patients with at least five-years undetectable plasma HIV-1 viral load

Group N = Average IMx ratio1 at start of HAART, ± st dev (range) Average IMx ratio ≥ 5 years undetectable viral load, ± st dev (range) P-value2
Patients without blips 30 37.48 ± 9.93 (16.83–52.33) 36.02 ± 7.79 (17.25–45.46) P = 0.95
Patients with 1–2 blips 50 33.30 ± 9.27 (13.08–53.39) 34.27 ± 7.56 (15.22–47.59) P = 0.29
All patients 80 34.87 ± 9.68 34.93 ± 7.65 P = 0.46
  1. 1 Antibody levels are calculated as ratios of the sample rate divided by the cutoff (= negative control). A sample is considered non-reactive if the ratio <1, and reactive when the ratio ≥ 1. The assay cutoffs are determined at each run, and vary slightly per assay and over time.
  2. 2 Two-tailed student's t-test.
