Data are expressed as (%) or median (IQR). was considered to be statistically significant. IQR = interquartile range; HE = hematoma expansion; Non-HE = nonhematoma expansion; m-CTD = mean CT densities; BHV = baseline hemorrhage volume; BS = blend sign; BHS = basal ganglia hemorrhage; IS = island sign; 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.
