Correlation between HIV suppressive activity and pVL.

<p><i>In vitro</i> HIV suppression assay mediated by <i>ex vivo</i> unstimulated CD8⁺ T cells at E:T ratio of 1:1 from HIV-infected volunteers (N = 19) were shown on the X-axis as percentages of HIV suppression. The pVL at the same time-point as the HIV suppression assay are presented on the Y-axis. Each symbol represents a single HIV-infected volunteer. Filled circles and open rectangles represent viraemic controllers and noncontrollers, respectively. Spearman’s rank test was analyzed as the statistic.
