In 2009, a paper was published in the then non-peer-reviewed journal "Medical Hypotheses" by Duesberg and four other researchers which criticized a 2008 study by Chigwedere et al., which found that HIV/AIDS denialism in South Africa resulted in hundreds of thousands of preventable deaths from HIV/AIDS, because the government delayed the provision of antiretroviral drugs. The paper concluded that "the claims that HIV has caused huge losses of African lives are unconfirmed and that HIV is not sufficient or even necessary to cause the previously known diseases, now called AIDS in the presence of antibody against HIV." Later that year, the paper was withdrawn from the journal on the grounds of it having methodological flaws, and that it contained assertions "that could potentially be damaging to global public health". A revised version was later published in "Italian Journal of Anatomy and Embryology".
