Comparison of cytokines and chemokines secreted by PBMC exposed to opsonised and unopsonised IE.

Ratios were calculated by dividing the cytokine or chemokine secretion detected in response to opsonised IE by that in response to unopsonised IE. Values represent median and IQR: only values which are significantly different to 1.0 are shown. For comparison between two paired groups a non-parametric Wilcoxon matched-pairs signed rank test was performed. * pNot significant (ns).
