Median viral load and CD4+ T cells in MHC class I HLA-B*57/5801-positive subjects with and without mutations at Gag residue 242. The upper error represents the 75th percentile. P-values were calculated using a Mann-Whitney rank sum test. Ninety-five percent confidence intervals on shift parameter were based on inversions of the Mann-Whitney rank sum tests (shown below the corresponding p-value for each time interval). Positive value of a shift parameter indicates that the values are greater in the group with mutations at Gag residue 242 than the group without. Measurements originated during the first 50 days p/s were excluded from analysis A. Plasma viral RNA load over four time intervals in relation to the estimated time of seroconversion: 50–200, 201–300, 301–400, and 401–500 days p/s. B. CD4+ T cell count over four time intervals in relation to the estimated time of seroconversion: 50–200, 201–300, 301–400, and 401–500 days p/s.
