Group 0 name Corresponds to the control (unexposed) group for case-control studies
Healthy controls
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
Diagnosis of all the cases was carried out using a CARS (Childhood Autism Rating Scale) score, DSM-5 approved AIIMS-modified INDT-ASD (INCLEN Diagnostic Tool for Autism Spectrum Disorder), and the ISAA (Indian Scale for Assessment of Autism) tool
Group 0 sample size Number of subjects in the control (unexposed) group
24
Group 1 sample size Number of subjects in the case (exposed) group
30
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
1 month
