3.3. The Primary and Secondary Hierarchical Composite Outcomes in Subgroups with Low and High Fish Intake
SECONDARY
A significant benefit of the n−3 fatty acid supplementation on the primary hierarchical composite outcome was obtained in the subgroup of participants with lower dietary fish intake (reciprocal win ratio [95% CI] of 0.79 [0.65 to 0.96]), from which the total number of wins and losses was 1,450,379 and 1,151,293, respectively, in the n−3 fatty acid vs. placebo groups (Reciprocal win ratios (95% CI) for the four secondary hierarchical composite outcomes in the participants with low and high fish intake at the baseline are summarized in
