a Variables are mean (±SD) or median (interquartile range).
b P < .05, compared with the SVaD group.
c P < .001.
d P < .05, compared with the HC group.
e P < .05, compared with the AD group.
f The Dunn method was used to correct multiple comparisons. In other cases, the Holm-Sidak method was used.
g P < .05.
