2. Figure 1
Mosaic plot of sclerosis scores by age group among 1203 living kidney donors. Sclerosis score defined as the total number of chronic histological abnormalities between (1) any global glomerulosclerosis, (2) any tubular atrophy, (3) interstitial fibrosis >5%, and (4) any arteriosclerosis. In the figure, a score of 0 is white, a score of 4 is orange, and intermediate scores are on a color intensity scale. The figure is used with permission.97

4. Figure 3
A comparison of estimated glomerular filtration rate (GFR) in two ‘normal’ cohorts according to age. (a) Men; (b) Women. Blue lines indicate mean, 90% UPL and LPL estimated glomerular filtration rate (eGFR; modification of diet in renal disease formula (MDRD), re-expressed equation) in healthy living donors. Orange lines indicate median, 5th, and 95th percentiles for ‘normal’ Caucasian community living adults from the Nijmegen Biomedical Study. UPL, upper probability limit; LPL, lower probability limit.
