Predictors of acute ischemic stroke vs. no ischemic stroke among patients with a neurologic symptom in the derivation and validation cohorts.

	Derivation cohort (AIS N = 44, total N = 827)			External validation cohort (AIS N = 62, total N = 817)
Variable	OR (95% CI)	P-value	AUC	OR (95% CI)	P-value	AUC
History of prior stroke	35.78 (7.23–176.95)	<0.001	0.83	19.2 (10.40–35.50)	<0.001	0.81
Age ≤ 60	3.75 (1.36–10.31)	0.011		2.31 (1.20–4.45)	0.012
