POC, presence of contractility; LES, lower esophageal sphincter; IRP, integrated relaxation pressure; RAC, repetitive antegrade contraction; RRC, repetitive retrograde contraction; FLIP, functional luminal imaging probe; EGJ-DI, esophagogastric junction–distensibility index; POEM, peroral endoscopic myotomy.

Data are presented as mean ± SD or n.
