Subclinical Atherosclerosis in Patients With Inflammatory Bowel Diseases: A Systematic Review and Meta-Analysis

What is it about?

We have read with great interest the meta-analysis published in a recent issue in Angiology by Wu et al.[1] We submitted this letter to support the findings of this meta-analysis, re-interpret these findings considering also our articles previously published, including a meta-analysis on arterial stiffness in patients with inflammatory bowel diseases, and to discuss about a potential methodological issue of the meta-analysis published by Wu et al. 1.
