CD patients were defined as having one of the following radiographic criteria: Cervical sagittal vertical axis (cSVA) &gt;4 cm, cervical kyphosis\/scoliosis &gt;10\u00b0\u00b0 or chin-brow vertical angle &gt;25\u00b0. The outcome assessed was whether a patient achieved both a good radiographic and clinical outcome. The primary analysis was stepwise regression models which generated a dataset-specific prediction model for achieving a good radiographic and clinical outcome. Model internal validation was achieved by bootstrapping and calculating the area under the curve (AUC) of the final model with 95% confidence intervals.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Seventy-three CD patients were included (61.8 years, 58.9% F). The final model predicting the achievement of a good overall outcome (radiographic and clinical) yielded an AUC of 73.5% and included the following baseline demographic, clinical, and radiographic factors: mild-moderate myelopathy (Modified Japanese Orthopedic Association &gt;12), no pedicle subtraction osteotomy, no prior cervical spine surgery, posterior lowest instrumented vertebra (LIV) at T1 or above, thoracic kyphosis &gt;33\u00b0\u00b0, T1 slope &lt;16 and cSVA &lt;20 mm.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
