SpletThe overall complication rate was 45%, mortality was 47%, and 29% of the patients died in the first 24 hours. Patients in the cryoprecipitate group received a lower volume of plasma (p < 0.01), and pRBCs (p < 0.01). Additionally, patients who received cryoprecipitate had lower rates of 24-hour mortality (p < 0.01) and in-hospital mortality (p < 0.
