Table 4 Treatment effects for pH metry and manometry at 3 months.

	Endocinch group (n = 17)		Sham group (n = 18)		p Value†
	Absolute change*	%	Absolute change*	%
Acid upright‡	−2.5 (6.1)	−22	−1.8 (6.6)	−14	0.74

LOS, lower oesophageal sphincter.

*Mean (SD).

†Statistical tests compared the mean differences in absolute change from baseline values between the Endocinch and sham groups.

‡Percentage of time oesophageal pH <4, off antisecretory drugs.
