# The regressions were considered significant at p < 0.05. Variation in the data was expressed as pooled SEM; Mean values in the same row with different superscripts differ significantly (p < 0.05). IELI: intraepithelial lymphocyte infiltration. a,b,c,d Means within the same row carrying different superscripts are significantly different at (p < 0.05).
