CD4 Recovery in HIV Treatment Figure 1. Correlations of pre-ART HIV disease progression and subsequent immune reconstitution following ART initiation in a Kenyan female sex worker cohort. A) Prior disease progression status does not correlate with the rate of CD4 recovery. Long-term non-progressors (LTNPs) are compared to normal progressors (those who did not meet the definition of LTNP). B) In univariate analyses, re-ART duration of immunosuppression (CD4,200) was inversely associated with CD4 recovery/month (r = 20.326, p = 0.004), while CD4 nadir correlated with CD4 recovery/month (r = 0.284, p = 0.012). On x-axis is either pre-ART duration of immunosupression (days) or CD4 nadir, while rate of CD4 recovery is on the y-axis (increase in cells/month). C) CD4 nadir (p = 0.007), but not length of immunosuppression (p = 0.873), was associated with the rate of CD4 recovery in multivariate analysis. doi:10.1371/journal.pone.0011434.g001 PLoS ONE | www.plosone.org 3 July 2010 | Volume 5 | Issue 7 | e11434
