National survey	Ref.	No. of HD patients	Outcome	Relative risk
Australia New Zealand Dialysis and Transplant Registry	Scott et al[62]	23046 (10-yr follow up)	Independent and significant association between a HCV(+) and all-cause mortality	HR = 1.25 (95%CI: 1.07-1.46, P = 0.004)

Dialysis Outcomes and Practice Patterns Study (DOPPS) from the United States (in three continents: Europe, Japan, United States)	Goodkin et al[64]	206134	a HCV(+) is an independent predictor of all-cause mortality	RR = 1.17 (P < 0.0159)
