Note: Data are the percentage and numbers in parentheses are the numbers of hemorrhage foci. Abbreviation: proSWMRI = proportion of dark signal intensity on susceptibility-weighted magnetic resonance imaging sequences
* The difference in the averages between the two groups was evaluated using the Mann-Whitney U test.
