Selection and evaluation of three interventional procedures for achalasia based on long-term follow-up

Table 1 Diameter of the narrowest cardia region before and after treatment with three interventional procedures, and dys-phagia score

Group	Diameter of cardia before and after treatment (mm)		Dysphagia score before and after treatment (grade)
A	3.2 ± 2.1	10.6 ± 3.8b	2.7 ± 1.4	0.9 ± 0.3b
B	3.4 ± 1.9	19.5 ± 1.1b	2.6 ± 1.3	0.4 ± 0.1b
C	3.1 ± 2.3	18.9 ± 3.5b	2.4 ± 1.3	0.5 ± 0.2b

^bP < 0.01 vs before and after treatment.
