This is a formal correction to a PLOS ONE research article assessing gold wrist-assisted PFNA in obese osteoporotic patients with intertrochanteric femur fractures. The correction replaces erroneous text in the Materials and methods (Study Design and Setting; Statistical analysis) and supplies corrected versions of Tables 1, 2 and 3 that contained previously incorrect statistical values. The correction notice itself does not provide additional outcome reinterpretation beyond updating the methods and tables.
The corrected Study Design and Setting subsection specifies that the work was a retrospective cohort study conducted at the Department of Orthopedic Trauma, Second Affiliated Hospital of Anhui Medical University. The institution is described as the Anhui provincial regional center and a leading institution of the China Trauma Rescue and Treatment Association, with responsibilities for regional referral reception, specialist outreach care coordination, and centralized postoperative follow-up management of treated patients.
Consecutive eligible patients recorded in the department’s clinical case registry and postoperative follow-up management process between October 2022 and October 2023 were retrospectively reviewed. The review included 12-month vital-status ascertainment. The study team retrieved, verified, and analyzed deidentified clinical records, available operative-related documentation, postoperative follow-up information, and outcome data under the approved protocol. The correction states that informed consent was obtained from all included patients.
The Statistical analysis subsection was corrected to report the software, variable handling, and tests used. All analyses were performed using SPSS version 24.0 and GraphPad Prism version 10.1.2.
The correction replaces earlier, incorrect statistical-methods text with the procedural details above. No new statistical results are synthesized in the correction text itself beyond the corrected tables described below.
The correction notice indicates that there were errors in statistical values reported in Tables 1, 2 and 3 of the original article. Corrected versions of these tables are provided with the correction and are available via the links and figure downloads embedded in the correction notice (Table 1: baseline data comparison; Table 2: perioperative data comparison; Table 3: postoperative follow-up data comparison).
The correction document references the corrected tables and provides downloadable PNG and TIFF files for each table. The correction text does not reprint numeric cells from those tables; readers seeking exact corrected values should consult the replacement table images or the corrected article files linked in the notice.
Ethics approval for the corrected study design is reported as granted by the Ethics Committee of Anhui Medical University (approval number SL-YX2022-137). The correction reiterates that patient records used for the retrospective review were deidentified and that informed consent was obtained from all included patients. Data sources included the Department’s clinical case registry, operative documentation, and the postoperative follow-up management system with 12-month vital-status ascertainment.
This correction was published on July 31, 2026, with DOI 10.1371/journal.pone.0355219. It pertains to the original article by Wu et al., cited in the correction as: Gold wrist-assisted PFNA reduces internal complications and enhances recovery in obese osteoporotic patients with intertrochanteric femur fractures.

Notes and limitations
The correction updates methodological descriptions and replaces tables containing statistical-value errors. It does not, within the correction notice text, restate or reinterpret clinical outcomes, effect sizes, or conclusions from the original article beyond supplying corrected tables. For precise corrected numerical results and any implications for interpretation, readers should consult the corrected Tables 1–3 and the related original article page linked in the correction notice.
