N: number of patients. The patients were considered with a low enlarged perivascular spaces (ePVS) burden when less than 11 ePVS were found at both the levels of basal ganglia and of periventricular parenchyma.
aMedian (interquartile range).
bPearson's Chi-squared test.
cWilcoxon rank sum test.
dFalse discovery rate correction for multiple testing.
