  1. 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.
  2. aMedian (interquartile range).
  3. bPearson's Chi-squared test.
  4. cWilcoxon rank sum test.
  5. dFalse discovery rate correction for multiple testing.
