Medians and 25th and 75th percentiles
^*No differences were seen between the groups at the baseline (Kruskal–Wallis test). Results are presented for 22 participants in the Cod group, 23 participants in the Salmon group and 20 participants in the Control group
^†Within-group changes are tested using the Wilcoxon’s signed-ranks test
^‡Changes within Cod group, Salmon group and Control group are compared using analysis of covariance (ANCOVA) with adjustment for baseline values after log transformation
