Table III.

The after/before ratios of the fecal short-chain fatty acid concentrations in hemodialysis patients who received synbiotics or prebiotics.

	Prebiotics (n = 6)	Synbiotics (n = 5)	p-value
Total short-chain fatty acids	2.1 ± 0.4	1.8 ± 0.1	0.60
Acetic acid	1.9 ± 0.3	2.5 ± 0.4	0.20
Propionic acid	2.3 ± 0.7	1.6 ± 0.1	0.35
Butyric acid	3.0 ± 0.7	1.6 ± 0.3	0.10
Isobutyric acid	3.0 ± 1.9	1.2 ± 0.3	0.37
Valeric acid	2.8 ± 1.1	0.8 ± 0.2	0.15
Isovaleric acid	3.9 ± 2.8	1.2 ± 0.5	0.40
