Case Definition Face-Off

A group of researchers led by Leonard Jason, PhD, used data mining techniques to determine which questions were most effective for accurately identifying cases using two definitions: the Canadian ME/CFS clinical definition (Carruthers, 2003) and the “empiric” definition proposed by CDC in 2005. Their findings show that the Canadian definition selects cardinal features of the illness better than the empiric and is better at discriminating cases from noncases.
