FMD is a repeatable measure of vascular function in healthy children and adults. However, repeatability can vary in adult populations with disease and inflammation, and the repeatability of FMD in children with a CID has not been explored.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>The objective of this study was to assess the repeatability of brachial artery FMD in children with a CID and their healthy peers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Participants with CID, including cystic fibrosis, inflammatory bowel disease, juvenile idiopathic arthritis, or type 1 diabetes (n\u2009=\u200952; age: 14.1\u2009\u00b1\u20092.1 years; sex: 48% F) and healthy controls (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200921; age: 12.3\u2009\u00b1\u20092.7 years; sex: 48% F), underwent two FMD assessments.
