  1. Differentially abundant OTUs between NG and PD subjects, belonging to the Indian cohort, identified using a negative binomial Wald test. A positive log2 fold change value indicates higher relative abundance of the OTU in PD subjects and vice versa. P values were adjusted for multiple testing using Benjamini-Hochberg correction. Up to top 15 OTUs (sorted according to mean abundance values) which are at least twofold enriched (padj < 0.05) either in the NG or the PD group are listed. The rightmost column depicts the log2 fold change (if any) for the same OTU in the Danish cohort with the respective padj values in brackets. “NA” in the rightmost column indicates absence (or limited abundance and/or ubiquity) of the OTU in the Danish cohort. OTUs marked with an asterisk (*) were also found to exhibit significant differential abundance between NG and PD groups in the Indian cohort after correcting for following factors—age, gender, waist-to-hip ratio, systolic BP, IL6, TNFα, LBP, and IAP.
