Fig. 2From: Accuracy of iohexol plasma clearance for GFR-determination: a comparison between single and dual samplingAgreement between SPSM and three-point plasma clearance. Notes: The solid lines and the dashed lines delineate the boundaries defined by P30 and P10, respectively. GFRi: the corresponding SPSM-GFR determined by single sample drawn at the time i (hr) after injection. mGFR: the 2-, 3- and 4-hr three-point plasma clearance of iohexol. Units are in ml/min/1.73m2Back to article page
