Table 2 Infection rates of type I and type II Helicobacter pylori in stepwise chronic gastric diseases

Groups	Total	H. pylori (+)	H. pylori (-)	Type IH. pylori (+)	Type IIH. pylori (+)
NAG	213	140 (65.7)	73 (34.3)	95 (67.9)^a	45 (32.1)
NAGE	96	75 (78.1)^c	21 (21.9)	47 (62.7)^a	28 (37.3)
PU	94	85 (90.4)^c	9 (9.6)	66 (77.6)^a^e	19 (22.4)
CAG	77	64 (83.1)^c	13 (16.9)	51 (79.7)^a^e	13 (20.3)
GC	43	38 (88.4)^c	5 (11.6)	32 (84.2)^a^e	6 (15.8)
Total	523	402 (76.9)	121 (23.1)	291 (72.4)	111 (27.6)

Data are presented as n (%).

^aP < 0.05, when type I H. pylori infection rate was compared with type II H. pylori infection rate in the same disease groups;

^cP < 0.05, when H. pylori infection rate was compared with the rate of control [non-atrophic gastritis (NAG)] group;

^eP < 0.05, when type I H. pylori infection rate was compared with the rate of NAG group. CAG: Chronic atrophic gastritis; GC: Gastric cancer; H. pylori : Helicobacter pylori; NAG: Non-atrophic gastritis; NAGE: Non-atrophic gastritis with erosion; PU: Peptic ulcer.
