Scatter plot showing the Ki-67 index assessed by computer-assisted image analysis (percentage of immunostained nuclear area in relation to the total nuclear area), in different types of canine perianal gland neoplasms: adenoma (n = 15), epithelioma (n = 15), and carcinoma (n = 12), and in control dogs (n = 13). Horizontal lines indicate the median and the interquartile range. abc Groups with no common superscript letter differ significantly by Dunn’s multiple comparison test (P < 0.05).
