The CFI study was a multicenter cross-sectional observational study, with the objective of establishing a well-characterized cohort of participants diagnosed with ME/CFS and controls with both clinical data and biologic specimens. The CFI was created and funded by the Hutchins Family Foundation and the clinical data and biospecimens were transferred to the National Institute of Neurological Disorders and Stroke. Investigators who request access to the CFI resource will be required to comply with the BioSEND Biospecimens User Agreement and/or the Data Use Agreement and to adhere to the Publication Policy.
