Group 0 name Corresponds to the control (unexposed) group for case-control studies
HC: household controls
Group 1 name Corresponds to the case (exposed) group for case-control studies
PD: individuals with Parkinson's disease
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
cohort 1: movement disorder specialists examined and confirmed the diagnosis of all PD participants at a baseline screening. Parkinsonian symptoms were assessed using the Unified Parkinson's Disease Rating Scale (UPDRS) and Hoehn and Yahr (H&Y) staging scale. cohort 2: PD participants were self-identified, verifying that they had received a PD diagnosis from a qualified physician.
Group 0 sample size Number of subjects in the control (unexposed) group
56
Group 1 sample size Number of subjects in the case (exposed) group
88
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
12 weeks
