a Data are median (IQR); P value for 2-wk change in scores by group (Oneway ANOVA for DASS data which were square root transformed to achieve normality; Kruskal Wallis test for POMS data which were not normally distributed)

b Change from baseline significantly greater for vegetarian diet than for omnivorous or fish diet (between group analysis)
