Relationship between weekly standardized Kt/V (stdKt/V) and equilibrated Kt/V (eKt/V) across dialysis modalities and schedules. With increasing frequency of therapy, lower eKt/V is required per dialysis session to achieve a similar stdKt/V. Abbreviations: CAPD, continuous ambulatory peritoneal dialysis; CHD, conventional hemodialysis; NHD, nocturnal hemodialysis; SDHD, short daily hemodialysis.

Relative increase in total solute removal (TSR) associated with a change from 4 to 8 hours of hemodialysis (HD): middle molecules versus small solutes. The impact of changes in TSR on conversion from 4 to 8 hours of HD is greater for middle molecules, such as phosphorus and β₂-microglobulin (β₂-M), compared with small solutes, such as urea and creatinine.
