Pearson’s r correlation between PAD and performance on neuropsychological tests.

Neuropsychological test	PAD correlation	95% CI	P Value	No. subjects
DSST	−0.080	(−0.104, −0.054)	4.3e−11	6849
TMT B	0.076	(0.051, 0.103)	3.1e−09	6076
TMT A	0.053	(0.027, 0.078)	3.8e−05	6076
TMT B - A	0.050	(0.024, 0.075)	1.3e−04	5918
Reaction time	0.030	(0.012, 0.047)	7.9e−04	12387

Negative DSST, positive TMT, and positive reaction time indicate worse performance
