- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- colorectal cancer patients who didn't take prebiotics (preoperative fecal sample)
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- colorectal cancer patients who took prebiotics (preoperative fecal sample)
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Patients with radiologic and pathologic diagnosis of CRC (preoperatively). Patients in the intervention group (prebiotic group) received a daily oral dose of 30 g prebiotic supplement (Hangzhou Niuqu Biotech Co., Hainengbo, China) containing fructooligosaccharide (25%), xylooligosaccharide (25%), polydextrose (25%), and resistant dextrin (25%) for 7 d from hospitalization to the day before the operation.
- Group 0 sample size Number of subjects in the control (unexposed) group
- 20
- Group 1 sample size Number of subjects in the case (exposed) group
- 18
- Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
- no treatment with antibiotics within 6 mo before surgery
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
Alpha Diversity
- Shannon Estimator of species richness and species evenness: more weight on species richness
- increased
