The letter to the editor made several comments regarding possible methodological issues in the recent article by Lin et al. determining the association between blood glucose variability and postoperative delirium in patients undergoing acute aortic dissection surgery with cardiopulmonary bypass, which is published in Journal of Cardiothoracic Surgery. 2021; 16(1):82. Our concerns included the lack of some important perioperative factors associated with postoperative delirium, the process of establishing multivariate model and the method of using the receiver operating characteristic curve analysis to assess the predictive performance of the standard deviation of blood glucose for the development of POD. We would like to invite the authors to comment on these and believe that clarifying these issues would improve the transparency of this study and interpretation of findings.
这封给编辑的信对林等人最近发表在《胸心血管外科杂志》上的文章提出了一些评论，文章探讨了在体外循环下进行急性主动脉夹层手术的患者中，血糖变异性与术后谵妄之间的关系。我们关注的问题包括缺乏一些与术后谵妄相关的重要围手术期因素、多变量模型的建立过程以及使用接收者操作特征曲线分析来评估血糖标准差预测术后谵妄发生的能力的方法。我们希望邀请作者对这些问题进行评论，并认为澄清这些问题将提高这项研究的透明度和对研究结果的解释。
