Table 3 PG1 in the serum and the PG1/2-ratio in association to gastric mucosal alterations

	Intestinal GC (n = 59)		Diffuse GC (n = 59)		Total (n = 118)
	PG1 (ng/ml)	PG1/2-ratio	PG1 (ng/ml)	PG1/2-ratio	PG1 (ng/ml)	PG1/2-ratio
Atrophy
(pos. vs. neg.)	50.4 vs. 120.6*	4.4 vs. 8.1*	77.9 vs. 141.6	7.0 vs. 11.0	56.2 vs. 136.6*	5.0 vs. 10.4*
IM
(pos. vs. neg.)	85.6 vs. 80.2	7.0 vs. 5.6	87.6 vs. 159.5*	8.4 vs. 11.5	86.3 vs. 147.8*	7.5 vs. 10.4*

Displayed are medians of PG1 in the serum and of the PG1/2-ratio for patients with intestinal type and diffuse type GC as well as for the whole study population (range not shown). For each line values for patients with and without atrophy or IM are given in direct comparison. Significant differences are marked with an asterisk applying a two-sided significance level of p < 0.05.
