Follow-up high resolution manometry (HRM) among patients without achalasia-type treatment.

FLIP motility classification	Normal	Weak	Obstruction with weak CR	Spastic-reactive	Inconclusive
Repeat/follow-up HRM
Progression (CCv4.0=Achalasia I, II, or III)	0	0	3 (50)	1 (17)	2 (33)
Consistent (CCv4.0=EGJOO)	0	0	2 (33)	0	4 (67)
Resolution (CCv4.0=not disorder of EGJOO)	2 (33)	0	1 (17)	0	3 (50)

Values reflect n (%). CCv4.0 – Chicago Classification version 4.0. CR – contractile response. EGJOO – esophagogastric junction outflow obstruction.
