Fig. 4From: Gastroesophageal flap valve reflected EGJ morphology and correlated to acid refluxGEFV grades correlated to AET% weakly, but had no impact on the values of four HRM metrics. EGJ subtypes correlated to supine AET% positively. The spearman rank correlation was used to explore the correlation between AET% and the GEFV grades and the correlation between supine AET% and EGJ morphologyBack to article page
