Flow fraction is defined as a ratio of the dialysate flow rate to the blood flow rate.
* The dialysate volumes in the 5 treatments per week column have been calculated using a flow fraction of 45% and a Kt/V of 0.6. ¶ The dialysate volumes in the 6 treatments per week column have been calculated using a flow fraction of 45% and a Kt/V of 0.5.
