Coagulation tests before and after prophylactic FFP transfusion. (a) Median platelets 108×103 µl−1 (IQR 68–171) before FFP, 101×103 µl−1 (IQR 75–147) after FFP transfusion. (b) Median INR 1.95 (IQR 1.70–2.60) before FFP transfusion, 1.65 (IQR 1.40–2.10) after FFP transfusion. (c) Median APTT 52.0 (41.0–72.0) s before FFP transfusion, 42.5 (35.3–50.0) s after FFP transfusion. (d) Median fibrinogen 2.4 μmol litre−1 (IQR 1.5–3.5) before FFP transfusion, 3.0 μmol litre−1 (IQR 2.1–4.9) after FFP transfusion.
