Comparison of anatomic abnormalities from discarded kidneys and randomly matched controls
| Biopsy Characteristic | Kidney Discarded for Biopsy Findings (n=83) | Randomly Matched Control (n=166) | P Valuea |
|---|---|---|---|
| Aortic plaque (61 pairs)b | 1.37±1.29 | 1.30±1.01 | 0.93 |
| Aortic plaque not mentioned | 32/83 (38.6) | 64/166 (33.6) | 0.99 |
| Renal artery plaque (78 pairs)b | 0.63±0.86 | 0.82±1.05 | 0.61 |
| Renal artery plaque not mentioned | 26/83 (31.3) | 57/166 (34.3) | 0.56 |
| Cysts noted | 27/83 (32.5) | 22/166 (13.3) | <0.001 |
| Capsular tear/hematoma noted | 2/83 (2.4) | 3/166 (1.8) | 0.75 |
| Normal, no anatomic abnormalities | 29/83 (34.9) | 91/166 (54.8) | 0.001 |
Data are presented as the fraction (%) or mean±SD.
a
P values for binary data were generated from logistic regression for repeated measures using generalized estimating equations and taking into account the nested correlation induced by kidney laterality within donor (5). P values for parametric data were generated from a signed rank test on the matched case-control differences for clustered data (6). See Supplemental Table 5 for details.
b
0, none; 1, mild; 2, moderate; 3, severe.
