In this article, a few sentences and one table note incorrectly used the more-than symbol (>) instead of the less-than symbol (<). The correct sentences and table note are as follows:
On page 3, Statistical Analysis section, “Pairwise Chi-squared tests with the Bonferroni correction of the significance level (P < 0.017) were used to compare the complications and reoperation rates between the 3 procedures.”
On page 3, Study Populations section, “The mean CCI ± SD was 6 ± 3.3 in the ACDF patients, 7.6 ± 3.9 in the laminectomy with fusion patients, and 6.9 ± 3.5 in the laminoplasty patients, P < 0.001.”
On page 5, Propensity-Score Matched Analysis section, “Wound complications at 1 and 3 months were less common in the ACDF group, < 2.4% and 2.8%, respectively, compared with laminectomy and fusion, 4.5% and 6%, and laminoplasty, 3.9% and 4.5%, respectively.”
On page 5, Propensity-Score Matched Analysis section, “Similarly, surgical site infections at 1 and 3 months were less common in the ACDF group, < 2.4% and < 2.4%, compared with laminectomy and fusion, 2.4% and 3.4%, and laminoplasty, 2.6% and 3%, respectively (Table 5).”
On page 8, Table 5, “The level of significance was set at P < 0.017 after Bonferroni correction.”
