- Condition The experimental condition / phenotype studied according to the Experimental Factor Ontology
- Response to transplant Response to transplant,response to transplant
- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- Non Rejection (Pre Rejection)
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- Rejection (Pre Rejection)
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Participants in the Rejection group were those who underwent kidney transplantation prior to rejection.
- Group 0 sample size Number of subjects in the control (unexposed) group
- 60
- Group 1 sample size Number of subjects in the case (exposed) group
- 32
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
- Kruskall-Wallis
- 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, chronic kidney disease, time, sex, Matched on: "Donor type" is not in the list (abnormal glucose tolerance, acetaldehyde, acute graft vs. host disease, acute lymphoblastic leukemia, acute myeloid leukemia, adenoma, age, AIDS, alcohol consumption measurement, alcohol drinking, ...) of allowed values.Donor type
