Efficacy of Endoscopic Radiofrequency Ablation for Treatment of Reflux Hypersensitivity: A Study Based on Rome IV Criteria

Table 4

Absolute differences in AET and LES pressure at baseline and 12 mo after treatment.

	Subjects with complete data	Absolute change from baseline		Carrying last value forward	Absolute change from baseline
AET	15	-0.1 (-1.2,1.1)	0.755	22	0.0 (-0.5,0.4)	0.755
LES pressure	15	1.9 (-0.6,4.4)	0.121	22	0.0 (0.0,3.2)	0.118
Total reflux episodes	15	-3.9 (-1.1,1.3)	0.677	22	-3.5 (-1.2,1.3)	0.679

AET: acid exposure time; LES, lower esophageal sphincter.
