Multivariate analysis: risk factors associated with stroke/TIA and cryptogenic stroke

Characteristic	Stroke/TIA		Cryptogenic stroke
	OR (95% CI)	P value	OR (95% CI)	P value
Female	1.51 (1.09 to 2.11)	<0.05	1.78 (1.19 to 2.67)	<0.01
Hypertension	1.53 (1.07 to 2.17)	<0.05	1.67 (1.05 to 2.64)	<0.05
Smoking	1.58 (1.06 to 2.36)	<0.05	1.55 (0.95 to 2.53)	0.08
≥200 PACs	1.97 (1.29 to 3.02)	<0.01	1.95 (1.16 to 3.28)	<0.05

Variables adjusted in the multivariate model: age, sex, excessive premature atrial complexes, hypertension, diabetes mellitus, smoking, dyslipidaemia, peripheral vascular disease and sleep apnoea.

PACs, premature atrial complexes; TIA, transient ischaemic attack.
