Mild Cognitive Impairment (MCI)
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
Data was obtained from four studies (PRJEB32675, PRJNA489760, PRJNA496408, and PRJNA734525). Group 1 refers to participants with enterotype Bacteroides (ET-B) having Mild Cognitive Impairment (MCI).

Group 1 sample size Number of subjects in the case (exposed) group
141
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
None.
