Scatter plot of the relative expression of miR-223 in the serum and colonoscopy score of dogs with large intestinal inflammatory bowel disease (IBD) (n = 26) 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), CCECAI = canine chronic enteropathy clinical activity index, miR = microRNA, r = Spearman’s rank correlation coefficient
