The authors regret an error on page 1008 in the second sentence of the Methods section regarding the institutional review board numbers. The sentence should read as follows:
The study protocol was approved by the institutional review boards of each hospital (approval no. H-2211-010-1373, 2022-11-024-001, and 2023GR0091, respectively), and the requirement for written informed consent was waived owing to the retrospective, anonymous study design.
The authors would like to apologise for any inconvenience caused.
