This study examines factors associated with possible diagnostic error in CeAD and evaluates its impact on patient outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p xml:lang=\"en\">We conducted a secondary analysis of the STOP\u2010CAD (Antithrombotic Therapy for Stroke Prevention in Cervical Artery Dissection) study, which is a multicenter international study of adult patients admitted with CeAD. Possible diagnostic error was defined as the presence of CeAD symptoms within 30\u2009days before the index CeAD diagnosis. The comparison group included patients diagnosed on their first medical encounter. Multivariable regression was used to identify factors associated with possible diagnostic error. Primary and secondary outcomes included ischemic stroke, death, and modified Rankin Scale score &lt;2.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      Of 4012 patients (mean age 47.5\u2009years, 44.6% female), 663 (16.5%) experienced possible diagnostic error.
