Beth Osborne Daponte, a demographer known for producing death estimates for the first Gulf War, evaluates the Lancet survey and other sources in a paper for the International Review of the Red Cross.[34] Among other criticisms, Daponte questions the reliability of pre-war estimates used in the Lancet study to derive its "excess deaths" estimate, and the ethical approval for the survey. She concludes that the most reliable information available to date is provided by the Iraq Family Health Survey, the Iraq Living Conditions Survey and Iraq Body Count.
