Figure 2. Box plot diagram shows the relative cytokine levels.Box plot of the relative cytokine levels on data set 1 (A; human inflammation kit) and data set 2 (B; Th-1/Th-2 kit). Relative cytokine levels were determined by dividing the individual cytokine level through the maximum cytokine level of that cytokine measured in the whole study group. After correction for multiple comparisons, the Kruskal–Wallis test revealed a statistically significant difference only for IL-10 in data set 1 and for INF-γ in data set 2 among the three study groups. The filled dots represent median values, the circles outliers, and the boxes 95% intervals. Abbreviations: IL=interleukin, TNF=tumor necrosis factor, INF=interferon.
