Values are expressed as mean ± SD.
Kt/V: spKt/V by Daugirdas. From urea clearance measured by UV absorbance and urea distribution volume measured by bioimpedance.
Ultrafiltration ratio: obtained from the formula [IDWG (mL/treatment time (h)]/post-dialysis weight (kg).
Urea reduction ratio and β2-microglobulin reduction ratio are obtained from the formula [(Solute)pre − (Solute)post/(Solute)pre] × 100.
DBP, diastolic blood pressure.
