Statistical Analysis
- Data transformation Data transformation applied to microbial abundance measurements prior to differential abundance testing (if any).
- relative abundances
- Statistical test
- Mann-Whitney (Wilcoxon)
- Significance threshold p-value or FDR threshold used for differential abundance testing (if any)
- 0.05
- MHT correction Have statistical tests be corrected for multiple hypothesis testing (MHT)?
- Yes
- Matched on Factors on which subjects have been matched on in a case-control study
- age, body mass index, smoking behavior, education level, sex
- Confounders controlled for Confounding factors that have been accounted for by stratification or model adjustment
- age, body mass index, smoking behavior, education level, sex
