- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- Neurotypical children
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- Children with Autism Spectrum Disorder (ASD)
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Children with ASD were assessed with the Autism Diagnostics Interview – Revised (ADI- Revised), Autism Diagnostics Observation Schedule (ADOS), Autism Treatment Evaluation Checklist (ATEC), and Pervasive Developmental Disorder Behavior Inventory (PDD-BI) to ensure that they had a diagnosis of autism.

- 20
- Group 1 sample size Number of subjects in the case (exposed) group
- 20
- Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
- 1 month
Lab analysis
- Sequencing type
- 16S
- 16S variable region One or more hypervariable region(s) of the bacterial 16S gene
