Practical Application of the COuGH RefluX Score for Patients with Laryngopharyngeal Symptoms: Real-World Assessment in Predicting GERD and PPI Response

The COuGH RefluX score has been validated to predict likelihood of gastroesophageal reflux disease (GERD) in patients with laryngopharyngeal symptoms (LPS) using parameters of Cough, Overweight, Globus, Hiatal Hernia, Regurgitation, and male seX. This study aimed to assess the real-world value of the COuGH RefluX score in predicting proton pump inhibitor (PPI) response in LPS patients.
