|---|---|---|---|---|
| 0 | 1 | 2 | 3 | |
| Arteriolar hyalinosisa | 446 (82.7) | 76 (14.1) | 15 (2.7) | 2 (0.3) |

| Vascular intimal thickening | 519 (97.5) | 21 (3.9) | 2 (0.3) | 0 (0.0) |

Data are presented as n (%). The mean number of glomeruli was per biopsy was 21.3±15.1 (range, 1–89).
a
Not all biopsies had sufficient numbers of glomeruli or arterioles to evaluate this lesion.
b
Grade 1, glomerulosclerosis of <10% of glomeruli; grade 2, glomerulosclerosis in 10%–25% of glomeruli; grade 3, glomerulosclerosis of >25% of glomeruli.
