Change in cognitive performance over one year between TIA and Controls.

	TIA median (Q1-Q3)	Control median (Q1-Q3)	p-value
MoCA decline	−1 (−3–2)	0 (−2–2)	.170
RAVLT Immediate Recall decline	−1 (−3–0)	−2 (−3–0)	.114
BVMT Total Recall decline	−5 (−7–0)	−1 (−6–2)	.060
BVMT Delayed Recall decline	−1 (−2–0)	0 (−1–1)	.021
TMTA (s) decline	−2 (−5–6)	0.2 (−6 - 5)	.885
TMTB (s) decline	−4 (−13–10)	2 (−10–16)	.053
DS Coding decline	−2 (−10–5)	−1 (−6–3)	.630

We defined decline as baseline values - follow-up values for MoCA, RAVLT, BVMT total recall, BVMT delayed recall, and DS coding. We defined decline as follow-up values - baseline values for TMTA and TMTB. Therefore, a negative value indicates that the score was better at follow-up than baseline (i.e., that cognition improved). A positive value indicates that the score was worse at follow-up than baseline.
