Thyrotoxic Atrial Fibrillation: Factors Associated with Persistence and Risk of Ischemic Stroke

Table 3

Multivariate analysis to determine factors associated with persistent atrial fibrillation.

Factor	Adjusted odd ratios	95% CI	value
Current/past smoker	4.9	1.8, 14	0.002
Lower free T4 at diagnosis	2.1	1.2, 3.5	0.008
Larger LA diameter	2.6	1.2, 5.5	0.014
Having a past episode of thyrotoxicosis	1.8	0.29, 2.1	0.642
LVDD	1.1	0.49, 2.2	0.925

Note. LVDD: left ventricular end diastolic diameter; LA: left atrium; .
