Patients underwent surgical treatment as indicated and were followed for 2 years. Cervical alignment, C2\u20137 ROM, JOA scores, JOACMEQ domains, and SF-36 scores were assessed. Clinical outcomes were compared using multivariate analyses adjusted for baseline factors. A subgroup analysis evaluated high-grade slip (\u22654 mm).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The Slip group was older and had more kyphosis and worse baseline lordosis and JOA score. Fusion was performed more frequently in the Slip group, which also showed a greater reduction in cervical ROM at 2 years. Adjusted postoperative JOA score, JOACMEQ, and SF-36 outcomes were comparable between groups postoperatively. Within the Slip group, high-grade slip (\u22654 mm) was associated with less JOA improvement in an exploratory subgroup analysis, whereas JOACMEQ and SF-36 scores were not influenced by slip severity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Neutral-radiograph-defined cervical anterolisthesis \u22652 mm was not independently associated with worse adjusted 2-year neurological, functional, or quality-of-life outcomes.
