Examining case definition criteria for chronic fatigue syndrome and myalgic encephalomyelitis

de Becker et al. 2010
A definition-based analysis of symptoms in a large cohort of patients with chronic fatigue syndrome 1578 CFS patients fulfilled the Fukuda criteria (called the "CFS group") and 951 (60.3% of the CFS group) fulfilled the Holmes criteria. The Holmes definition was found to be better than the Fukuda at differentiated CFS patients from the patients with Chronic Fatigue without CFS.
