Abstract 23, February, 2024. Research Square has withdrawn this preprint as concerns have been raised (https://pubpeer.com/publications/8DFB6F002B66C99339E8A9696B3310) about the alignment between this study and another by Shi et al. (2020) "Dexmedetomidine improves early postoperative neurocognitive disorder in elderly male patients undergoing thoracoscopic lobectomy". Experimental and Therapeutic Medicine, 20, 3868-3877 (https://doi.org/10.3892/etm.2020.9113). Despite both studies citing the same clinical trial registration, they detail divergent research protocols and outcomes. Due to these significant discrepancies with the information registered for the trial, we have opted to withdraw the paper, and this preprint should not be cited as these important issues need to be clarified in a revised publication.
