The Association between Job Strain and Atrial Fibrillation: Results from the Swedish WOLF Study

Table 3

The estimated association between accumulated exposure to job strain and the risk of atrial fibrillation. Hazard ratios (HR) with 95% confidence intervals (95% CI), based on a subsample from the WOLF Norrland study population with baseline measure in 1996–1998 (t1) and repeated measure in 2000–2003 (t2), .

	HR; (95% CI)^*	P value; for trend
Subsample with repeated measurements, 47 events
Unexposed to job strain at both t1 and t2	1 (ref)	0.06
Job strain at either t1 or t2	1.68 (0.83–3.40)
Job strain at both t1 and t2	2.28 (0.70–7.44)
