Values are expressed in grams. P values between-group comparisons were analyzed by unpaired t test or Mann–Whitney U test. Soy and soy products: Soy and soy products including natto. Fish: Total fish amount including fatty fish which contain sum of eicosapentaenoic acid (EPA), docosapentaenoic acid
(DPA) and docosahexaenoic acid (DHA) over 1.0 g per 100g edible portion. § Values are calculated as pure ethanol amount in grams.
There were missing data for 3 of PJD and 2 of JD participants at 3 months, and 6 participants each in both group at 6 months.
