Impact of Helicobacter pylori infection on ghrelin and various neuroendocrine hormones in plasma

Table 3 Correlations of ghrelin with other peptides in plasma in terms of H pylori status.

	Gastrin	Somatostatin	Leptin	IGF-1	Chromogranin A
H pylori positive	0.015 (NS)	0.076 (NS)	-0.239 (NS)	0.064 (NS)	0.285 (P<0.05)
H pylori negative	0.025 (NS)	0.100 (NS)	-0.353 (P<0.05)	0.272 (P<0.05)	0.073 (NS)
Total	0.018 (NS)	0.086 (NS)	-0.318 (P<0.05)	0.097 (NS)	0.200 (NS)

Data are correlation coefficients and (P values) of the correlations. IGF-1: insulin-like growth factor-1, NS: not significant.
