2. Figure 1
Comparison of clearance measurements in the Residual Kidney Function Study. (A) Scatterplot of 24-hour plasma clearance of iohexol (CLiohexol) versus 24-hour urinary CLiohexol. Dashed lines and shaded areas represent the linear fit and confidence interval of the linear regression. (B) Plot of extrarenal CLiohexol (24-hour plasma CLiohexol - 24-hour urinary CLiohexol) versus 24-hour urinary CLiohexol. Positive numbers represent overestimation of 24-hour urinary CLiohexol; negative numbers, underestimation. Dashed line represents fit from a median quantile regression of the extrarenal CLiohexol on 24-hour urinary CLiohexol. Abbreviation: RMSE, root-mean-square error.
