Why did Science partially retract the XMRV-chronic fatigue syndrome paper?

If past experience is any indication, billions of pixels will be spilled in the coming days as scientists and advocates debate the latest twist in the story of XMRV, or xenotropic murine leukemia-related virus, and chronic fatigue syndrome (CFS). Today’s news is that Science is partially retracting a 2009 paper by Judy Mikovits and colleagues, including Vincent Lombardi, purporting to show a link between the virus and the syndrome — a paper about which they issued an Expression of Concern in May. The retraction is of a table and a figure — more on that in a bit.

Alberts and Science Executive Editor Monica Bradford had first suggested that Mikovits and her co-authors retract the paper voluntarily. “Science feels it would be in the best interest of the scientific community,” they wrote in a 26 May letter. Mikovits was livid and questioned Alberts’s motives. “Who wrote that letter? I don’t think it was Science,” she says. The co-authors thought the retraction request was premature, too. “What if we walk away from this based on contamination and it’s not contamination?” Lombardi asked. “You’ve got to give us time to figure this out.”

Alberts stresses that they floated the retraction idea because Science already planned to publish the Expression of Concern. “It wasn’t a public call for retraction,” he notes, emphasizing that the recipients shared it with the media. He also does not think it would have been premature, although he says it’s often a tough call whether to retract a paper. “Ultimately, it requires expert judgment and a lot of sensitivity to the issues,” he says. “We had lost confidence in the results.”

Science asks authors to retract XMRV-chronic fatigue syndrome paper; when they refuse, issue Expression of Concern

It’s Expression of Concern Day here at Retraction Watch. Earlier, we reported on two such notices regarding the complicated case of Milena Penkowa. And now we learn that a 2009 Science paper linking XMRV, or xenotropic murine leukemia-related virus, to chronic fatigue syndrome  (CFS) that has been dogged by questions from the start, is the subject of another Expression of Concern. Such expressions, as we’ve noted, often, but do not always, precede retractions.

The Wall Street Journal reports that Science editor-in-chief Bruce Alberts and executive editor Monica Bradford asked the authors of the paper to retract it last week, after two studies scheduled to published in this week’s Science threw even more doubt onto the findings. But “study co-author Judy A. Mikovits of the Whittemore Peterson Institute for Neuro-Immune Disease said “it is premature to retract our paper,” leading Alberts to issue the Expression of Concern, which begins: Continue reading Science asks authors to retract XMRV-chronic fatigue syndrome paper; when they refuse, issue Expression of Concern
