*1: Raw fish (times/week) + fish-paste products (times/week) + dry-fish (times/week). *2: When calculating values, age was always included in the models as a covariate. Trend of association was assessed by a regression model assigning consecutive integers to the levels of the weekly fish consumption. *3: Geometric mean.
