Group 1 name Corresponds to the case (exposed) group for case-control studies
Participants on ketogenic diet
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
To determine the impact of dietary intervention on human immunity and microbiota, this group of participants were placed on a ketogenic diet, and would later be switched to a vegan diet.

Group 1 sample size Number of subjects in the case (exposed) group
10
