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

	Subjects with complete data	Absolute change from baseline	P	Carrying last value forward	Absolute change from baseline	P
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.
