What the research team did was employ a computer algorithm normally used for data mining and clustering to sift through the answers on Jasons DePaul Symptom Questionnaire (DSQ). The DSQ contains 54 ME/CFS symptoms, which patients rank by frequency and severity. (These are the two parameters not included in the Fukuda definition, and which Lily Chu correctly insisted be included in any definition produced by the IOM.)
