Continuous variables are reported as median (interquartile range). Categorical variables are reported in terms of frequency (percentage). SCT – standard coagulation tests; PLT – platelet count (109/L); PTI – prothrombin time index (%); INR – international normalized ratio (value); APTT – partial thromboplastin time (s); FIB – fibrinogen (g/L).
