From: Sex differences in Alzheimer’s disease: plasma MMP-9 and markers of disease severity
Sex modified the association between plasma MMP-9 and CSF p-tau181 and Aβ42. A Higher free plasma MMP-9 levels correlated with lower CSF p-tau181 levels for men (green), but there was no association between free MMP-9 and CSF p-tau181 levels among women (blue). B There was a trend for a significant correlation between higher total MMP-9 and higher CSF p-tau181 levels among women with MCI, but there was no association in men with MCI. C Higher free plasma MMP-9 levels were associated with higher CSF Aβ42 among men with MCI (green) but there was no correlation among women with MCI (blue)
