As promised, the Lancet has published a correction to the 2nd Lancet study:
Burnham G, Lafta R, Doocy S, Roberts L. Mortality after the 2003 invasion of Iraq: a cross-sectional cluster sample survey. Lancet 2006; 368: 1421–28–The Methods section of this Article (Oct 21, 2006) stated that “Participants were assured that no unique identifiers would be gathered.” Upon review, it was determined that a significant number of the surveys contained names of respondents and household inhabitants. This was a lapse in the authors’ obligations to protect participants. However, to the authors’ knowledge, the completed surveys remained in possession of the research team at all times and there were no known breaches in confidentiality.
