- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- Alzheimer’s disease
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- Amnestic mild cognitive impairment (aMCI)
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Patients with aMCI who met the previously published National Institute on Aging and Alzheimer’s Association criteria (2011) for “MCI due to AD,” with memory deficits as the only complaint of cognitive impairment.
- Group 0 sample size Number of subjects in the control (unexposed) group
- 32
- Group 1 sample size Number of subjects in the case (exposed) group
- 32
- Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
- 3 months
