The purpose of this investigation was to determine the relationship between aspiration and seven other variables indicative of pharyngeal stage dysphagia. Additionally, we looked at the relationship between aspiration and oral stage dysphagia. Multiple logistic regression analysis identified five independent predictors of aspiration that were significant at the p = 0.05 level: vallecular stasis, reduced hyoid elevation, deviant epiglottic function, diffuse hypopharyngeal stasis, and delayed initiation of the pharyngeal stage of the swallow. A linear trend was observed in that, as the severity of vallecular stasis, pyriform sinus stasis, diffuse hypopharyngeal stasis, or delayed initiation of the pharyngeal stage of the swallow increased, the proportion of patients who aspirated also increased. A stepwise logistic regression model furnished estimates of the odds ratio for each independent variable and can be used by clinicians to calculate the risk of aspiration in patients who demonstrate pharyngeal stage dysphagia.
本研究的目的是确定误吸与其他七个表明咽期吞咽困难的变量之间的关系。此外，我们还研究了误吸与口腔期吞咽困难之间的关系。多元逻辑回归分析确定了五个在p = 0.05水平上具有显著意义的误吸独立预测因素：会厌谷淤滞、舌骨抬高减少、会厌功能异常、下咽弥漫性淤滞以及吞咽咽期起始延迟。观察到一种线性趋势，即随着会厌谷淤滞、梨状窦淤滞、下咽弥漫性淤滞或吞咽咽期起始延迟的严重程度增加，误吸患者的比例也增加。逐步逻辑回归模型提供了每个自变量的比值比估计值，临床医生可使用该模型来计算表现出咽期吞咽困难的患者发生误吸的风险。
