Figure 3

The mucosal height and the thickness of the sub-epithelial collagen band are shown as assessed by two observers who were blinded to the aim of the study (observer ratings indicated as black squares and dots). The results obtained in specimens from the 2003 colonoscopy are connected with dotted lines and those from the 2008 procedure with continuous lines. The semi-quantitative assessment of the lymphocytic infiltrate is shown as table at the bottom of the figure. The results on the semi-quantitative analysis of intraepithelial plasma cells, eosinophils and neutrophils are not shown as they parallel the results for the lymphocytic infiltrate.
