Table 1. Demographics of intracranial hemorrhage patients by gender.
Males developed ICH at a younger age than females (62.2 ± 13.2 vs. 66.3 ± 15.3; P<0.001). Males had a higher occurrence for ICH at all age groups up to 80 years old, beyond which there was a higher occurrence in females. Gender did not interact with ethnicity to cause a difference in ICH.

1Statistical tests: ethnic and age group, chi-square test; age, 2-sample t-test
*Statistical significance due to gender disparity in >80 group.
#Mild GCS impairment is defined as GCS >12, moderate impairment as 9–12 and severe as ≤ 8
