- Abbreviations: NT, no treatment; G, glucose infusion; GI, glucose-insulin infusion; A-site, arterial site; V-site, venous site of the dialyser; RF, removal fraction.
- *P < 0.001 for comparison of insulin and insulin aspart concentrations between the A- and V-site at each time point and study day.
- **The RF of insulin did not differ between study days and were similar for insulin and insulin aspart. From 0 to 120 min the RF declined for both insulin (p < 0.001, overall) and insulin aspart (p = 0.006), whereas the changes in the RF from 120 to 240 min did not reach statistical significance. Data are expressed as mean ± SD for insulin concentrations and mean (95% confidence interval) for RF.
