Group 1 name Corresponds to the case (exposed) group for case-control studies
Type I Diabetics
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
type 1 diabetes was diagnosed according to the criteria of the American Diabetes Association and the positivity of at least two persistent, confirmed anti-islet autoantibodies (anti-insulin autoantibodies, GAD autoantibodies, or tyrosine phosphatase autoantibodies). MODY2 children were diagnosed by suggestive clinical history, negative anti-islet autoantibodies, and positive genetic testing. Healthy control subjects were children with negative anti-islet autoantibodies,
Group 0 sample size Number of subjects in the control (unexposed) group

Group 1 sample size Number of subjects in the case (exposed) group
15
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
3 months
