Determining Peak Cough Flow Cutoff Values to Predict Aspiration Pneumonia Among Patients With Dysphagia Using the Citric Acid Reflexive Cough Test

Objective To investigate the clinical usefulness of the peak cough flow generated during the citric acid reflexive cough test (0.28 mol/L) by determining the appropriate cutoff values that could accurately predict aspiration pneumonia within the first 6 months after onset. Design Retrospective analysis of a prospectively maintained database. Setting University-affiliated hospital. Participants Patients (N=163) with first-ever diagnosed dysphagia...
