Summary of adequacy assessment of renal allograft biopsies
| Period | Total biopsies (n) | Adequate biopsies (n,%) | Suboptimal biopsies (n,%) | Inadequate biopsies (n,%) | Difference in adequacy (%)* | p value |
|---|---|---|---|---|---|---|
| 1 | 20 | 15 (75%) | 0 (0%) | 5 (25%) | NA | NA |
| 2 | 270 | 152 (56%) | 81 (30%) | 37 (14%) | −19% (4, 41) | = 0.16 |
| 3 | 49 | 34 (69%) | 9 (18%) | 6 (12%) | +13% (2, 28) | = 0.11 |
*Change of percentage of adequacy in the period in question compared to the preceding period, i.e. comparing period 2 to period 1, and comparing period 3 to period 2.
