Table 2 Comparison of esophageal manometry findings between the RESP and N-RESP groups

	RESP group (n = 17)	N-RESP group (n = 12)	P value
Gastroesophageal reflux GER (%)
Baseline	9.4 (7.4-13.5)	11.7 (7.6-15)	NS
7th post-PEG day	2.5 (0.6-3.8)	8.1 (7.4-9.2)	< 0.001b
No. of reflux episodes/h
Baseline	8 (3-10)	2.9 (2-4.4)	0.020a
7th post-PEG day	1.3 (0.5-2)	2.9 (2.3-3.4)	0.002a
No. of reflux episodes > 5 min
Baseline	7 (4-9)	3.5 (2-6)	0.045a
7th post-PEG day	1 (0-2)	3 (1.5-5)	0.003a
