^*The prediction using objective cough measures and CNSS score were unadjusted (adjusted) by demographic and clinical characteristics (eg, age, race, clinical signs of aspiration, speech problems, disorientation, and cognitive deficit) in the unadjusted (adjusted) logistic regression model. See Table 3 for abbreviations not used in the text.
