Expressions of E-cadherin and MMP-7 according to reflux symptom index.

Markers	13 or Lower than 13 (n = 8)	Higher than 13 (n = 14)	p-Value
E-cadherin			0.007
Weak	0	8
Strong	8	6
MMP-7			0.004
Weak	6	2
Strong	2	12

Staining intensity scores were as follows: weak = no staining and mild stain intensity, strong = moderate and strong stain intensity. Statistical analysis was performed using SPSS version 20.0 (IBM SPSS, Armonk, NY, USA). Statistical significance was considered to be p < 0.05.
