Table 4.

Cox regression models for myocardial infarction, ischemic stroke or congestive heart failure among patients (n=12,283) aged 45–104 years with atrial fibrillation and levothyroxine prescription compared to those without a prescription (referents) attending the 75 primary health care centers between January 1^st 2001 and December 31^st 2007

		Model 1	Model 2	Full Model
		HR (95% CI)	HR (95% CI)	HR (95% CI)
Myocardial infarction	All	1.06 (0.87; 1.30)	1.05 (0.86; 1.29)	1.04 (0.84; 1.30)
Ischemic stroke	All	0.88 (0.74; 1.05)	0.89 (0.75; 1.07)	0.86 (0.71; 1.04)
Congestive heart failure	All	1.12 (0.98; 1.28)	1.10 (0.96; 1.26)	1.08 (0.88; 1.07)

Model 1 is adjusted for age and sex, Model 2 for age, sex and co-morbidity (for congestive heart failure also interaction term between age and diabetes), and Full Model for age, sex, co-morbidity, individual socio-economic factors, and neighborhood socio-economic status. Hazard ratios (HRs) in Cox models, and 95% CIs are shown.
