Figure 6. The sera and stools of IBS patients indicate higher levels of the chemokine CXCL16 than that of healthy volunteers.

Figure 6

Sera and stools from IBS patients and healthy volunteers were evaluated for CXCL16 concentration using quantitative ELISA (R&D Systems, Minneapolis, MN). Mann Whitney test showed significant difference between the medians of the healthy volunteers versus ID-IBS (P<0.0001) and PI-IBS (P<0.0001). The medians of ID-IBS versus PI-IBS were not significantly different (P = 0.6219). Error bars indicate median values with range.
