However, accidents can occur due to lack of concentration and poor reactions. The Cognitive Failures Questionnaire (CFQ) measures self-reported cognitive deficits in the completion of simple everyday tasks. We investigated the relationship between drivers\u2019 cognitive capability and the severity of SDB, sleepiness and self-reported driving incidents.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>348 patients (n=150, exploratory; n=198, validation) considered for a trial of continuous positive airway pressure and 173 controls (exploratory (n=105), validation (n=68)) matched for age and driving experience completed questionnaires that included the CFQ and a driving questionnaire.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Compared to controls, patients had a higher total mean\u00b1\n                      <jats:sc>sd<\/jats:sc>\n                      CFQ score (37\u00b118\n                      <jats:italic>versus<\/jats:italic>\n                      28\u00b112, p=&lt;0.0001, 95% CI \u221213.3\u2013\u2009\u22127.3) and more self-reported driving incidents (accidents and\/or near misses in the last year) (38%\n                      <jats:italic>versus<\/jats:italic>\n                      10%; OR 2.6, 95% CI 2.79\u20138.34; p=0.0005).
