The table lists Kendall’s tau-b rank correlation coefficient (τ) as a measure of association, and the level of significance (p).

^*p < 0.05;

^**p < 0.001.

AF, fibrinogen-positive area fraction; CAA, cerebral amyloid angiopathyi; CELL, cellular labelling score for deep grey matter (caudate-putamen) and for deep subcortical white matter; SVD, small vessel disease.
