Figure 3a:

(a) Graph shows colon segments with ¹⁹F signal (gray) have higher histologic scores than do segments without ¹⁹F signal (black) for most of the scoring parameters. Significant differences were observed for the area involved (* P = .036) and mononuclear cell (MNC) infiltration (** P = .009) criteria. PMNC = peripheral blood mononuclear cell. (b) Total colitis score was calculated by summation of the scores for all criteria. Graph shows colon segments with ¹⁹F signal had significantly higher total colitis (* P = .006) and dysplasia (** P = .013) scores than did segments without ¹⁹F signal. Error bars indicate standard error of the mean.
