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/V_{urea}; eKtV, equilibrated Kt/V_{urea}.
