Subjects were considered to show a positive blue sign when areas of blue were observed against the yellow‐green background and surrounding the red spots. A comparison of the ratio of positive blue sign for both groups (Group A: 15.4% ± 37.6%, Group E: 94.1% ± 24.2%) showed a statistically significant increase in the ratio in Group E (<italic>P</italic> < 0.001).</p> </sec> <sec id="den12124-sec-0004" sec-type="section"> <title>Conclusion</title> <p>The results of the present study suggest that blue sign may be effective in the differential diagnosis of angioectasia and enteritis in patients with red spots.</p> </sec> </abstract>
