Latent class analysis of a heterogeneous international sample of patients with myalgic encephalomyelitis/chronic fatigue syndrome (Leonard Jason team)

Almost certainly the case, I think. Seems impossible for one person, whether patient, clinician, researcher, or carer, to take it all in.

Would be useful.

Though I suspect that eventually we will see that it is a continuum, maybe with distinct peaks (groupings), reflecting different states or phases. Stable (to different degrees), relapsing-remitting, slowly varying over time. That kind of thing.
