- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- Control (healthy group)
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- OCD T0 (Baseline)
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Patients with Obsessive-compulsive disorder (OCD), which is a neuropsychiatric condition characterized by intrusive and unwanted thoughts (termed obsessions) and repetitive behaviors or mental acts (termed compulsions), which are carried out to at least partially alleviate the anxiety or distress brought on by the obsessions. Timepoint 0 was the baseline timepoint prior to three months of pharmacological treatment and cognitive behavioral therapy (referred to as T0).
- Group 0 sample size Number of subjects in the control (unexposed) group
- 33
- 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
- LEfSe
- Significance threshold p-value or FDR threshold used for differential abundance testing (if any)

- 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
- 2.0
- Matched on Factors on which subjects have been matched on in a case-control study
- age, sex
