Nitric oxide (NO) and asymmetric dimethylarginine (ADMA) concentrations measured during the study

	HD		HDF
	Before treatment	After treatment	Before treatment	After treatment
NO(μmol/L)	30.3 ± .76	12.23 ± 5.7*	29.4 ± 18.25	11.55 ± 5.54*
ADMA(μmol/L)	0.69 ± 0.2	0.55 ± 0.16*	0.64 ± 0.18	0.59 ± 0.15*

During hemodiafiltration and conventional hemodialysis both NO and ADMA concentrations were observed to decrease significantly two hours after completion of the treatments (*p < 0.001).

HD: hemodialysis, HDF: haemodiafiltration.
