This reproducible R Markdown analysis was created with workflowr (version 1.7.1). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.


Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.

Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.

The results in this page were generated with repository version 87e9060. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.

Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish or wflow_git_commit). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:

Note that any generated files, e.g. HTML, png, CSS, etc., are not included in this status report because it is ok for generated content to have uncommitted changes.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a chronic, disabling illness affecting an estimated 1–3 million Americans. It is marked by persistent fatigue, post-exertional malaise, cognitive impairment, pain, and a range of immune, metabolic, and neurological symptoms.

Onset often follows infection or occurs gradually in adulthood. Research has identified biological abnormalities in ME/CFS, including immune dysregulation, altered cytokine profiles, metabolic dysfunction, and neuroinflammation.

Family studies suggest a genetic component, with first-degree relatives of ME/CFS patients at increased risk.

Methods

Bulk RNA-Seq Analysis

Peripheral blood RNA was collected from 29 ME/CFS patients for transcriptomic profiling. Bulk RNA sequencing was performed by Vantage.

We used the nf-core/rnaseq pipeline for secondary analysis. This pipeline was modified to run on UAB’s Cheaha high-performance computing cluster.
