This study aimed to develop a non-invasive machine learning model incorporating Peptest™ and GerdQ scores to facilitate GERC detection, particularly in primary care and resource-limited environments where MII-pH testing is not readily available.Methods210 chronic cough patients were enrolled between September 2022 and June 2024. GERC diagnosis followed established guidelines, and salivary pepsin levels were measured via Peptest™. Feature selection was performed using the Boruta algorithm (hereafter referred to as Boruta), a method based on random forest (RF), designed to identify relevant variables by comparing them to random shadow features. The selected optimal features were then evaluated using nine ML models, including logistic regression (LR), RF and others. Model performance was assessed through area under the curve (AUC), decision curve analysis (DCA), and calibration curves.Results73 (34.76%) patients had GERC.
