Data are expressed as (%), , or median (interquartile range (IQR)). was considered to be statistically significant. IQR = interquartile range; m-CTD = mean CT densities; BHV = baseline hemorrhage volume; BS = blend sign; BHS = basal ganglia hemorrhage; IS = island sign; HE = hematoma expansion; SBP = systolic blood pressure; DBP = diastolic blood pressure; APTT = activated partial thromboplastin time; PT = prothrombin time; TT = thrombin time; FIB = fibrinogen; INR = international normalized ratio; Hcy = homocysteine.
