- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- The participants in this group consumed 1500g of fresh strawberries in the first two weeks, 2500g from week 3 to week 9, and 3750g in week 10. Additionally, they had 100g of Freeze-dried strawberries in week 1 and 200g in week 2 and week 10.
