Multiple regression analysis for inflammation in relation to cytokine levels in Helicobacter pylori–positive patients with nonulcer dyspepsia.

		Antrum		Corpus
Histology	Explanatory variable	PRC ± SE	P	PRC ± SE	P
MNC	IL-18 protein level	0.0026 ± 0.0005	<.001	0.0011 ± 0.0007	.004
	IL-18 mRNA level	0.54 ± 0.13	<.001	0.51 ± 0.08	<.001
PMN	IL-18 protein level	0.0004 ± 0.0002	.092	0.0009 ± 0.0005	.006
	IL-18 mRNA level	0.37 ± 0.16	.041	0.59 ± 0.18	.009
	IFN-γ mRNA level	…	…	0.34 ± 0.19	.056

NOTE. Final models are presented. Adjusted for age, sex, and H. pylori density at the same topographical site. The partial regression coefficient (PRC) provides an estimate of the expected results of the mononuclear cell (MNC) scores. For example, in the antrum, MNC scores would be expected to increase 0.54 if interleukin (IL)–18 mRNA scores increase by 1. IFN, interferon; PMN, polymorphonuclear leukocyte.
