Changes in free fraction.

<p>Solute concentration and plasma clearance during isohydric and standard dialysis.</p

Changes in pH and bicarbonate concentration during standard and isohydric dialysis.

<p>Individual lines are actual subject data, heavy lines are adjusted means from mixed model. The black vertical line represents the time during isohydric dialysis at which the bicarbonate buffer concentration was changed.</p

Changes in free fraction during isohydric and standard dialyses.

<p>Heavy lines connect fitted means from the mixed model analyses. Colored lines represent individual patient data.</p

Proportion of variation accounted for by mixed models predicting free concentration from either pH or total concentration.
