Table 1 Comparison of basic data between patients with and without the blend sign on baseline CT

From: Post-operative re-bleeding in patients with hypertensive ICH is closely associated with the CT blend sign

Characteristics Blend sign positive (n = 41) Blend sign negative (n = 85) P value

Systolic pressure (\( \overline{\mathrm{x}} \)±s) 177.59 ± 26.62 171.78 ± 28.65 0.145
Diastolic pressure (\( \overline{\mathrm{x}} \)±s) 102.56 ± 16.71 97.92 ± 16.98 0.151
Time to baseline CT (\( \overline{\mathrm{x}} \)±s) 10.93 ± 2.84 11.74 ± 2.63 0.790
Baseline ICH volume (\( \overline{\mathrm{x}} \)±s) 33.68 ± 21.57 33.19 ± 22.32 0.190
Glasgow coma scale score (\( \overline{\mathrm{x}} \)±s) 9.83 ± 3.38 11.16 ± 2.77 0.020
Ruptured into the ventricle (%) 16(39.0) 47(55.3) 0.006
NIHSS on admission (\( \overline{\mathrm{x}} \)±s) 14.12 ± 4.62 13.38 ± 4.13 0.391
  1. CT indicates computed tomography and ICH indicates intracerebral haemorrhage
