  • The data are presented as the means ± SD. spKt/V and eKt/V differed significantly between centers (P = 0.018 and P = 0.006 for spKt/V and eKt/V, respectively). For the three centers combined, the difference in spKt/V and eKt/V between the two dialysate flow rates was not significant (−0.024 with 95% confidence limits of −0.064 and 0.024 for spKt/V and −0.014 with 95% confidence limits of −0.051 and 0.023 for eKt/V). spKt/V, single-pool Kt/Vurea; eKtV, equilibrated Kt/Vurea.
