Group 0 name Corresponds to the control (unexposed) group for case-control studies
Healthy men without Parkinsons's Disease.
Group 1 name Corresponds to the case (exposed) group for case-control studies
Men with Parkinson's Disease.
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
Only early stage PD men who were naïve to L-DOPA therapy as diagnosed according to the UK Brain Bank criteria.
Group 0 sample size Number of subjects in the control (unexposed) group
28
Group 1 sample size Number of subjects in the case (exposed) group
31
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
The use of antibiotics in the past three months in principle was an exclusion criterion. However, we included three PD patients and three controls despite the intake of antibiotics for one to three days in a period of 28–34 days prior to feces sampling as the omission of those cases from the analyses did not change any result
