FIG. 4.

Association between viral loads and HIV-1-specific CTL numbers at the time of blood draw. Plots on the upper row are correlations between viremia (log₁₀) levels and Env, Pol, Gag, and Nef specific CTL numbers in the B*35-PY group of patients; those on the lower row are the same correlations for the B*35-Px group of patients. Each open circle represents one patient. There is a significant inverse correlation between Gag-specific CTL and viral load in the B*35-PY group (r = −0.614; P = 0.009).
