GFR measurement in patients with CKD: Performance and feasibility of simplified iohexol plasma clearance techniques
Fig 5
Bland–Altman plots with 8-hour vs. 7, 6 and 5 hours after iohexol infusion.
Bland–Altman plots and limits of agreement between GFR values obtained with the one-compartment models shortened to 7, 6, or 5 hours versus the GFR values obtained with the standard 8-hour procedure. Upper panels show data obtained from all available clearance measurements (Overall); Lower panels show data obtained from the first, baseline, clearance measurements available from each individual patient (Baseline Analyses).
