Summary of 164 subjects’ follow-up by UGI series study 12 + -1.5 months after the first UGI series.

Variables	No GER (n = 102)	GER-s (n = 20)	GER-d (n = 42)	P value
Morphologic type
1 (n = 75)	49 (48.0%)	11 (55.0%)	15 (35.7%)	.271
2 (n = 39)	8 (7.8%)	9 (45.0%)	22 (52.4%)	<.001∗
3 (n = 13)	8 (7.8%)	0	5 (11.9%)	.327
5 (n = 37)	37 (36.3%)	0	0	NA

GER-d = GER episodes noted, complicated with either mucosal erosions or strictures or both, over the distal esophagus, GER-s = GER episode observed, with smooth distal esophageal contour without mucosal erosions, strictures or scarring of the lower esophagus, no GER = no reflux was observed, and the esophageal contour was smooth, NA = not assessed, UGI = radiographs of the upper gastrointestinal tract.

^∗Indicates a significant association between GER-s, GER-d and Type 2 morphology (P < .001).
