4. Figure 3
Correlation between the different methods to assess free water transport. The correlation between free water transport as a percentage of the total fluid transport in the first hour and the difference in net ultrafiltration between a 3.86% and a 1.36% glucose exchange (left). The correlation between free water transport as a percentage of the total fluid transport in the first hour and the maximum dip in D/P sodium using a 3.86% glucose solution (right).

5. Figure 4
Bland and Altman plot of the differences between the calculations of free water transport in the first hour of a dwell versus their means. An underestimation of free water transport of about 10% was present when no correction for sodium diffusion is made. No systematic errors were found.
