Patients responded to questionnaires including PRO-JOA, EuroQOL-5D, Neck Disability Index, and Short Form-12 preoperatively and at &gt;12 months postoperatively. Spearman\u2019s rho and Bland-Altman analyses were used to investigate the correlations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Preoperative JOA and PRO-JOA scores were 10.8 and 10.6, respectively, with Spearman\u2019s rho of 0.74. Similarly, postoperative JOA and PRO-JOA scores were 13.3 and 12.9, respectively, with Spearman\u2019s rho of 0.68. However, the recovery rates for JOA and PRO-JOA scores were 42% and 27%, respectively, with Spearman\u2019s rho of 0.45. Compared with other PROs, JOA and PRO-JOA scores were moderately correlated. The minimum clinically important difference was 2.5 for JOA score, 3.0 for PRO-JOA score, 42% for JOA recovery rate, and 33% for PRO-JOA recovery rate. Bland-Altman analyses revealed that limits of agreement were \u22124.3 to 4.7, \u22123.4 to 4.3, and \u221275% to 106% for the preoperative score, postoperative score, and recovery rate, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>PRO-JOA score can also be used as a disease-specific scoring measure instead of JOA score.
