Hazard Ratios (HR) and 95% Confidence intervals from Cox regression models for the effect of CD4+ cellular responses to CSP on clinical malaria episodes.

<p>Hazard Ratios are adjusted by age (as a continuous variable), distance from the dispensary (continuous variable), bednet use, location of residence (in 4 groupings) and, when all vaccinees are included in an analysis, by vaccination group.</p><p>“At least TNF+” refers to all cells producing TNF, including polyfunctional cells (i.e. producing TNF with IL2, TNF with IFNγ, or TNF with IFNγ and IL2). The parallel definition applies to “at least IL2+”. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0052870#s2" target="_blank">Results</a> that are significant after a Bonferroni correction (i.e.<0.002) are shown in bold.
