aP < 0.05 vs functional heartburn (FH).

bP < 0.01 vs FH.

HRM, high-resolution manometry; ERD, erosive reflux disease; NERD, non-erosive reflux disease; RH, reflux hypersensitivity; LES, lower esophageal sphincter; EGJ-CI, esophagogastric junction contractile integral; IRP, integrated relaxation pressure; DCI, distal contractile integral; DES, distal esophageal spasm; IEM, ineffective esophageal motility.

Data are presented as mean (SD) or number (%).
