This repository contains: 1. Data used for analyses from: A) 16S rRNA gene amplicon analysis after paired-end Fastq files were truncated, filtered, denoised, and merged ["1-ASV_Counts.xlsx"] B) Untargeted metabolomics as provided by Metabolon ["2-UntargetedMetabolomics.xlsx"] C) Precision SCFA analysis ["3-PrecisionSCFA.xlsx"] D) Clincal demographic data of the study cohort ["Clinical Demographics.csv"] 2. Detailed results of univariate analyses in sub-folder "Univariate analysis results" for clinical data, untargeted metabolomics data, SCFAs, and ASVs 3. Detailed results of predictive analysis in subfolder "Predictive Analyses results", including per-fold performance results ("9-PredictiveResults.xlsx") and analysis of predictive features for ASVs ("10-ASVsPredictiveAnalysis.xlsx"), untargeted metabolites ("11-MetabsPredictiveAnalysis.xlsx"), targeted SCFAs ("12-SCFAPredictive Analysis.xlsx"), clinical data ("13-DemoPredictiveAnalysis.xlsx") and all data ("14-AllDataPredictiveAnalysis.xlsx") 4. Data for generating all figures and analyses in the publication ("GenFigure&AnalysesData")
