Michael M. Meguid

In 2015, the case was finally brought to a close in Meguid's favor, and made public in the October 2015 British Medical Journal article 'Ranjit Chandra: how reputation bamboozled the scientific community'. In January 2016, The Lancet published a retraction of the paper, 'Effect of vitamin and trace-element supplementation on immune responses and infection in elderly subjects', that Meguid had originally questioned.

In 2005, Meguid, as Editor-in-Chief of Nutrition, retracted a paper by Ranjit Kumar Chandra titled "Effect of vitamin and trace-element supplementation on cognitive function in elderly subjects". Chandra filed suit and a decade of discussion about scientific misconduct followed, with the Chandra case being mentioned in 90-plus articles. In 2015 Chandra was found guilty of misconduct. The Lancet then retracted the study they had published in 1992.
