Multivariable analysis to predict discordance between biopsy and pathological grading (n = 822) with internal biopsies considered as the reference group
| Variable | OR (95% CI) | p value |
|---|---|---|

| ||
| External sampling and internal review | 1.62 (1.18–2.23) | 0.003 |
| External sampling and no internal review | 3.27 (2.12–5.05) | <0.0001 |
| Age | 0.99 (0.97–1.01) | 0.2 |
| Preoperative prostate-specific antigen | 0.99 (0.98–1.01) | 0.3 |
| Pathological stage | ||
| T2 | Reference | |
| T3a | 1.52 (1.10–2.09) | 0.011 |
| T3b | 1.37 (0.80– 2.34) | 0.3 |
| Pathological ISUP grade | ||
| 1 | Reference | |
| 2–3 | 10.58 (2.40–46.67) | 0.002 |
| 4–5 | 14.79 (3.19–68.61) | 0.001 |
| Prostate weight | 1.00 (0.99–1.01) | 0.8 |
OR = odds ratio; CI = confidence interval; ISUP = International Society of Urological Pathology.
