The authors’ second round of corrections were not incorporated into the published article. The article has been updated to include changes in the “Data Collection and Outcome Assessment,” “Discussion,” and “Limitation” sections. The corrected sections are presented below:
Data Collection and Outcome Assessment
“Clinical outcomes were assessed using the visual analog scale (VAS) and the Oswestry Disability Index score at 12 months postoperatively. PSL and clinical outcomes were assessed at 12 months postoperatively.”
Discussion
“We recommend that surgeons utilize already-available preoperative CT scans to obtain pedicle HU values as a complementary tool to DXA for preoperative BMD assessment, in order to streamline patient selection for augmentation strategies. According to the results of the McNemar test, the threshold may be set at 110 (originally 106.32) for clinical convenience.”
Limitation
“Future multicenter prospective studies with larger sample sizes and standardized protocols for monitoring medication adherence and treatment duration are warranted to further validate the effectiveness and applicability of our findings.”
“Finally, we only analyzed some of the factors associated with PSL and other well-established influencing factors, such as pedicle screw size, insertion technique, postoperative sagittal alignment, and spinopelvic parameters, were not included in the statistical analysis due to limitations in sample size.”
