Clinical significance and usefulness of soluble heparin binding-epidermal growth factor in gastric cancer

Table 3 Serum levels of soluble heparin-binding epidermal growth factor-like growth factor between normal mucosa/chronic superficial gastritis and chronic atrophic gastritis or between normal mucosa and chronic superficial gastritis

Groups	Serum sHB-EGF1 (pg/mL)
Normal mucosa/CSG (n = 30)	86.4 ± 73.5
CAG (n = 30)	102.9 ± 93.1
P value2	0.449
Normal mucosa (n = 15)	83.1 ± 59.0
CSG (n = 15)	89.7 ± 87.6
P value2	0.811

¹Tested value is expressed as the mean ± SD.

²An independent sample t-test is applied to compare the differences of means between two groups. P < 0.05 (two-tailed) was considered statistically significant. sHB-EGF: Soluble heparin-binding EGF-like growth factor. CSG: Chronic superficial gastritis; CAG: Chronic atrophic gastritis.
