- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- Enterotype 2 (enriched in healthy controls)
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- Enterotype 1 (enriched in AMD patients)
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Individuals clustered into enterotype 1 based on genus-level gut microbiome profiles using PAM(Partitioning Around Medoids) clustering with Jensen-Shannon distance. This group was predominantly composed of AMD patients and showed higher relative abundance of Escherichia-Shigella.
- Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
- 3 months
Lab analysis
- Sequencing type
- 16S
- 16S variable region One or more hypervariable region(s) of the bacterial 16S gene
- V3-V4
- Sequencing platform Manufacturer and experimental platform used for quantifying microbial abundance
- Illumina
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)?
- No
