- Group 1 name Corresponds to the case (exposed) group for case-control studies
- 40 week old (old) mice 6 months after antibiotic treatments
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- 40-week old mice (old) administered treated with broad-spectrum antibiotics metronidazole (500 mg/L) and ciprofloxacin (200 mg/L) for 10 days.
- Group 0 sample size Number of subjects in the control (unexposed) group
- 5
- Group 1 sample size Number of subjects in the case (exposed) group
- 5
- Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
- Mice were not previously given antibiotics before the study
Lab analysis
- Sequencing type
- 16S
- 16S variable region One or more hypervariable region(s) of the bacterial 16S gene
