Moshe Carmel, Basem Hijazi, Narges Azzam, Tawfik Khoury, Amir Mari: Chicago Classification Version 4.0 Improves Stratification of Ineffective Esophageal Motility Patients into Clinically Meaningful Subtypes: A Two-Center International Study (Dysphagia )

The 4th iteration of the Chicago Classification (CC v4.0) for esophageal motility disorders offers more restrictive criteria for the diagnosis of Ineffective Esophageal Motility (IEM) compared to version 3.0 (CC v3.0). In light of the updated criteria for IEM, we aimed to characterize and compare the patients who retained their IEM diagnosis to those who were reclassified as normal motility, and to evaluate the clinical impact of the newly introduced CC v4.0.
