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
- LEfSe
- 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
- LDA Score above Threshold for the linear discriminant analysis (LDA) score for studies using the popular LEfSe tool
- 3.0
Alpha Diversity
- Simpson Estimator of species richness and species evenness: more weight on species evenness
- unchanged
Signature 1
Source: FIG 2 (D)
Description: LEfSe analysis identified the differences in abundance between I-PJS and NI-PJS patients (LDA > 3.0).
Abundance in Group 1: decreased abundance in With Intussusception (I-PJS)
