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
autoimmune hepatits cases
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
The diagnosis of AIH was made if patients conformed with (1) 1999 revised International Autoimmune Hepatitis Group (IAIHG) score ≥10 and/or (2) 2008 IAIHG simplified AIH score ≥6 and/or (3) histological features indicative of AIH.
Group 0 sample size Number of subjects in the control (unexposed) group
98
Group 1 sample size Number of subjects in the case (exposed) group
91
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
4 weeks

Lab analysis

Sequencing type
16S
16S variable region One or more hypervariable region(s) of the bacterial 16S gene
V3-V4

Statistical Analysis

Data transformation Data transformation applied to microbial abundance measurements prior to differential abundance testing (if any).
