People who ate less than 1.5 servings of fish per week benefited. For these people, there was about 19% of the observed reduction in cardiovascular disease, and about 40% reduction in heart attacks.
The second study
The second study, called the REDUCE-IT experiment, involved more than 8,000 middle-aged and elderly people with high levels of triglycerides who were at or at risk of heart disease. The study aimed to see if a high dose of about 4 grams could protect against cardiovascular disease compared to a placebo.
