| Potential pre-procedure bleeding risk variable | blood-stained (n = 60) | non-blood stained (n = 147) | statistical significance |
|---|---|---|---|
| Mean anti-thrombotic medication score | 1.21 (0–4) | 1.19 (0–4) | p = 0.91 |
| Mean pre-procedure INR | 1.24 (1–4.2) | 1.21 (1–3) | p = 0.63 |
| Mean pre-procedure APTT | 30.74 (19–93.8) | 31.74 (19.6–56.2) | p = 0.50 |
| Mean pre-procedure platelet count | 341 x 109 (72–614) | 293 x 109 (44–1156) | p = 0.06 |
