The database consisted of nationwide inpatient data collected from &gt;1000 acute care hospitals in Japan. This DPC database contains information regarding the hospitalization course, such as diagnosis, treatment, medical history, complications, and hospitalization outcomes. We included 866 CFD patients whose impaired levels were specified. We compared the outcomes between the patients whose CFD occurred in the upper cervical levels (\u201chigh\u201d group) and the intermediate-low levels (\u201clow\u201d group). This study determined 121 pairs of patients after one-to-one propensity score matching (PSM). The main outcomes included inhospital death, 30-day mortality, and major complications after admission. The secondary outcomes were the length of hospital stay, discharged home rate, and improvement in Barthel index.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      No differences in inhospital death and 30-day mortality were found between the high and low groups, even after adjusting for PSM (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &gt; 0.05, respectively).
