Figure 2

The relation between baseline glomerular filtration rate (GFR) and GFR change rate. The figure shows the best linear unbiased predictors (BLUPs) of random slopes and intercepts, indicating the relation between baseline GFR (the random intercept) and GFR change rate (random slope) in a linear mixed model after using within-subject mean centering for the time variable.
