Cerebral Autoregulation by Gender

Autoregulatory Index
Gender ARImca ARIbas Mean ± SD
Boys 0.98 ± 0.03 0.92 ± 0.12 0.95 ± 0.09
Girls 0.92 ± 0.10 0.97 ± 0.06 0.95 ± 0.08
Mean ± SD 0.95 ± 0.08 0.94 ± 0.10
p = 0.02

Girls have higher ARImca than boys whereas boys have higher ARIbas than girls. ARI = autoregulatory index; MCA = middle cerebral artery; BAS = basilar artery.
