Scatter plots of the relative expression of miR-146a in the colonic mucosa and serum of dogs with large intestinal inflammatory bowel disease (IBD) (n = 21) as determined by Spearman’s rank correlation. Statistical significance was defined as p < 0.05. AU = arbitrary units (which represent the expression of each miR normalized to U6sn RNA internal control), miR = microRNA, r = Spearman’s rank correlation coefficient
