Baseline NK Cell percentages by HIV-1 RNA Outcome following Regimen Simplification.

<p><a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0095524#pone-0095524-g001" target="_blank">Figure 1</a> compares the baseline NK cell levels, defined by CD3-CD56+CD16+ cells, and virologic outcome (HIV-1 RNA below or above 50 copies/mL, throughout the study). The circles represent each study participant with either sustained HIV-1 RNA suppression during the trial and those participants who developed detectable viremia following treatment simplification. The difference in the median NK cell levels between the groups with detectable and suppressed viremia was statistically significant with a p-value of 0.002. The median level is noted by the line in the scatterplot for each group.
