Correlation of plasma HIV-1 RNA levels with CD4+ lymphocyte HIV-1 DNA levels.

(A) Relationship of plasma HIV-1 RNA to CD4+ lymphocyte HIV-1 DNA levels before stem cell mobilization and harvesting. (solid line) Fit of data by linear regression (P < .0001;r = 0.79). (B) Relationship of plasma HIV-1 RNA levels to the level of CD4+ lymphocyte HIV-1 DNA during stem cell mobilization and harvesting (days 4 through 7) for each subject. (solid line) Fit of data by linear regression (P < .0001; r = 0.68). (dashed lines) 95% confidence intervals for the regressions. This analysis used only data pairs for which quantifiable values of both HIV-1 RNA and DNA levels were available.
