  • The data are presented as the means ± SD. Ionic dialysance and Kt/VID differed significantly between centers (both P < 0.001). For the two centers combined, the difference in ionic dialysance between the two dialysate flow rates was significant (6.89 with 95% confidence limits of 3.98 and 9.81), whereas the difference for Kt/VID was not significant (0.035 with 95% confidence limits of −0.029 and 0.099).
