The study of 150 patients with chronic fatigue syndrome and another 150 healthy volunteers should be complete by early 2012, said Ian Lipkin, a professor of epidemiology at Columbia University in New York, who is leading the effort. Until the research is complete, its too soon to know whether there is a link between a virus and chronic fatigue, he said.
Calls to retract the paper at this point are premature, said Lipkin, director of Columbias Center for Infection and Immunity, in a telephone interview. We need to let this study take its course, look at the data in a coherent fashion and figure out what it tells us. While interesting, the publications dont dissuade us from continuing our work.
