- Condition The experimental condition / phenotype studied according to the Experimental Factor Ontology
- Clinical treatment Clinical treatment,clinical treatment
- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- Parkinson's disease (PD) patients treated with levodopa only (PD_L)
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- Parkinson's disease (PD) patients treated with both levodopa and Entacapone (PD_LE)
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Entacapone, one of the most common drugs distributed among patients with Parkinson’s disease, is a peripherally acting catechol-O-methyltransferase (COMT) inhibitor that is used in addition to levodopa to control symptoms

Description: ASVs that significantly differed in abundance before and after the treatment of entacapone. 108 ASVs were identified as significantly different after the treatment of entacapone. 3 ASVs that were not assigned taxonomy to the genus level had a decrease in abundance. They were removed for plotting purposes. Genus and phylum level classification of the significant ASVs are provided in the plot. Genus in bold are unique to our study when compared with Weis et al. (2019).
Abundance in Group 1: increased abundance in Parkinson's disease (PD) patients treated with both levodopa and Entacapone (PD_LE)
