CDCs Chronic Fatigue Syndrome Wichita Clinical Study

The Wichita Clinical Study data were collected during a 2-day in-hospital clinical assessment study conducted from December 2002 to July 2003 in Wichita, KS, USA (referred to as Wichita Clinical Study). Assessments included clinical evaluation of each subject's medical and psychiatric status, sleep characteristics and cognitive functioning. Laboratory testing evaluated neuroendocrine status, autonomic nervous system function, systemic cytokine profiles, peripheral blood gene expression patterns and polymorphisms in genes involved in neurotransmission and immune regulation. Evaluation was performed without knowledge of disease classification.
