However, recent studies suggest potential for neck pain improvement with CDR. This study aimed to compare postoperative improvements in neck pain and disability between patients undergoing anterior cervical discectomy and fusion (ACDF) and CDR.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Predominant neck pain was defined as neck pain equal to or greater than arm pain preoperatively (visual analog scale [VAS]) and neck disability index (NDI) &gt; 20. Patients with predominant neck pain who underwent 1- or 2-level ACDF or CDR for radiculopathy between 2017 and 2023 were included. Patient-reported outcomes (NDI, VAS) were assessed up to 1 year postoperatively. Inverse probability of treatment weighting (IPTW) was used to control for confounders. Linear mixed-effect models were applied to compare postoperative outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 179 patients (105 ACDF, 74 CDR) were included. Both groups showed significant improvement in NDI and VAS neck scores from baseline to 1\u00a0year (NDI: \u03b2 = \u22121.81,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001; VAS neck: \u03b2 = \u2212.26,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001).
