Table 1 Demographics of first and recurrent ischemic stroke patients, and for strokes GCNK region, 2005

	Ischemic stroke patients n = 2,269^a, ^b
Age in years, mean ± SEM	70.2 ± 0.35
Black, N (weighted %)	492 (20.1 %)
% Female, N (weighted %)	1,266 (55.4 %)
Pre-stroke disability (mRS ≥ 2), N (weighted %)	1142 (47.7 %)
History of prior stroke, N (weighted %)	429 (19.5 %)
retrospective NIHSSS, median (25th, 75th percentile)	3 (1, 7)

^a = Data are presented as weighted mean and standard error, raw n (weighted percentage) and weighted median (25th, 75th percentile)
^b = For each patient, these summary statistics pertain to the first ischemic stroke in study period; 2,148 patients had only 1 event, 108 patients had 2 events, and 13 patients had 3 events
