The control group consisted of 30 adults hospitalised with acute cardiac symptoms. Data were derived from spirometry, the 150 mL timed water swallow test, a cookie swallow test and a dyspnoea questionnaire (modified Medical Research Council (mMRC)). Scores from the 10-item Eating Assessment Tool (EAT-10) were calculated to assess patient perception of swallowing dysfunction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Self-reported swallowing dysfunction and clinical signs thereof were more common in COPD patients than in the control group (67%\n                      <jats:italic>versus<\/jats:italic>\n                      23% and 80%\n                      <jats:italic>versus<\/jats:italic>\n                      37%, respectively; p\u22640.001). Clinical signs of swallowing dysfunction in the group with acute exacerbation of COPD were associated with self-reported swallowing dysfunction (p=0.02) and xerostomia (p=0.04). Dyspnoea (mMRC \u22652) was more common among the COPD patients (90%\n                      <jats:italic>versus<\/jats:italic>\n                      47%, p&lt;0.001).
