  • a USRDS, US Renal Data System.

  • b Dhingra et al. (5). Because the difference between graft and fistula in patients without diabetes was not found to be statistically significant, 1.0 was assumed.

  • c Author calculation based on modality mix in Dhingra sample.

  • d USRDS (15) Tables 4.12, I0.15 for all modes of access, and author calculations assuming constant hazard rate for specific modes.
