⁺Based on the FFQ item that asked about intake from 1) fried fish - fried fish, shrimp or seafood (including sandwiches), 2) baked/grilled fish - broiled or baked fish, shrimp, or seafood (including sandwiches), and 3) tuna - canned tuna, tuna casserole, or tuna salad (including sandwiches)

^*RRs adjusted for age, kcals/day, gender, BMI, smoking, alcohol consumption, physical activity level, income level, education level, presence of chronic disease, insurance coverage, gender, and total meat intake per day. The log-likelihood ratio test was used to evaluate the significance of the interaction terms for sex and race with fish or n-3 LCFA intake
