Study (First author[ref]) Study population (Age population) Country Follow-up Estimation of n-3 PUFAs dietary intake Main results(Risk of AF a in the highest intake vs. the lowest intake group)
Cardiovascular Health Study(Mozaffarian [36]) 4,815 subjects(= 65 years) USA 12 years Food Frequency Questionnaire Lower AF risk with broiled fish RR 0.70 (95% CI; 0.53-0.91) p=0.008
Danish Study (Frost [38]) 47,949 subjects (mean age 56 years) Denmark 5.7 years Food Frequency Questionnaire Increased AF risk RR 1.34 (95% CI; 1.02-1.76) p = 0.001
