XMRV & Chronic Fatigue Syndrome: Negative Study #3, But So What?

I’m starting to feel like a broken record — a third study European study has failed to uncover a link between XMRV and chronic fatigue syndrome. Is this the nail in the coffin of this theory? Was all the hype and excitement for nothing? Are we back to square one?

Not in the least. This Dutch study, like the 2 British ones before it, didn’t even attempt to replicate the original XMRV study from the Whittemore Peterson Institute (WPI). It was the first to use similar testing methods, but the inclusion criteria were rather different — which could mean that we’re looking at 2 radically different populations.
