- FIGURE 1.
Scatterplots of mGFR vs. eGFR values for MDRD and CKD-EPI (SCr), CKD-EPI (CysC), and CKD-EPI (CysC+SCr). Graphs in left-hand column use UV/P 99mTc-DTPA method for mGFR as reference. Corresponding graphs in right-hand column use plasma 99mTc-DTPA method. Line of identity (dashed line), linear line fit (solid line), and 95% confidence intervals (thin dotted lines) are shown for each set of comparisons.
