Effect of Helicobacter pylori infection on gastric epithelial cell proliferation

Table 1 BrdU LI% of the patients (^-x±s)

	LI%	case number
H. pylori-positive	6.14 ± 1.21a	57g
vacAs1a positive	8.00 ± 1.46ae	24
vacAs1a negative	4.51 ± 0.86c	27
H. pylori-negative	2.43 ± 0.61	43

^aP < 0.001 vs H. pylori negative patients;

^cP < 0.01 vs H. pylori negative patients;

^eP < 0.02 vs non-vacAs1a H. pylori patients;

^gvacAs1a were not examined in 6 cases because of loss of specimens.
