Histology Scores and Epithelial thickness per treatment group. (a) Results from visual scoring histological analysis of injury based on an ordinal value scoring system (0,1,2). Statistical analysis of ordinal variable (0,1,2) histology scores was by the mixed model to test the treatment effects and perform multiple comparisons. Tukey adjustment was used for the p-values in the multiple comparisons. (b) Epithelial thickness measured quantitatively on H&E histology single sections. Single factor ANOVA followed by Tukey's post hoc test was applied to test for statistical significance. Statistical significance with p < 0.05 is represented with * and p < 0.01 with **.
