aIndicated statistically significant between transient hiatal separation and hiatal hernia groups by Dunn’s test.

Statistical significance among these three groups was assessed by Kruskal-Wallis test with post hoc analysis via Dunn’s test.

EGJ-CI, esophagogastric junction contractile integral; LES, lower esophageal Sphincter; IRP-4s, 4 seconds integrated relaxation pressure; MRS, multiple rapid swallow.

Data are presented as median (interquartile range: Q1, Q3) or n (%).
