Table 2 Characteristics of patients who received hemodialysis

Age (yr)	68.8 ± 11.2
Male/female (n/n)	68/40
Duration of hemodialysis (yr)	8.7 ± 8.6
Body weight (kg)	51.4 ± 11.4
Body mass index (kg/m2)	20.2 ± 3.5
Albumin (g/dL)	3.4 ± 0.4
Total cholesterol (mg/dL)	159.5 ± 36.4
Cholinesterase (U/L)	230.3 ± 87.2
Infection of H. pylori: non/past/present	29/30/49
Acyl-ghrelin (fmol/mL)	25.9 ± 19.8
Desacyl-ghrelin (fmol/mL)	256.2 ± 158.4

Values are presented as mean ± standard deviation. Non, negative with all three detection systems (anti-H. pylori IgG serological test, rapid urease test and culture test) and endoscopic gastric mucosal atrophy; past, negative with all detection systems for H. pylori and positive for endoscopic gastric mucosal atrophy; present, positive results were observed with at least one of the detection systems. H. pylori: Helicobacter pylori.
