Absolute T_½ Compared Between Responders and Nonresponders

Parameter	Responders	Nonresponders	P
Before G-POEM TG T_½	169 ± 42	218 ± 80	0.11
Before G-POEM PG T_½	149 ± 37	141 ± 27	0.68
After G-POEM TG T_½	131 ± 42	108 ± 37	0.31
Before G-POEM RI	0.924 ± 0.069	0.794 ± 0.059	0.006
After G-POEM RI	0.924 ± 0.070	0.886 ± 0.070	0.19

TG = total gastric emptying. PG = proximal gastric emptying
Data are average ± SD. There were insufficient complete data to compare PG T_½ after G-POEM between responders and nonresponders.
