Another Green Tea Study Retracted

A study suggesting that green tea catechins reduce the invasive potential of human melanoma cells was recently retracted by the journal PLos One on December 31, 2018 due to concerns over the accuracy of the data. It's the twelfth study by former University of Alabama researcher Singh Katiyar to be retracted since 2012, and one of four green tea studies by Katiyar retracted in 2018. 

A University of Alabama investigation into Katiyar's papers found that "Certain published images within those papers were not substantiated by available data, or the scientific conclusions of the publication were not supported," according to a report by told Retraction Watch.

None of the retracted papers were included in ConsumerLab's Green Tea Review, which includes detailed information about clinical studies on green tea.

The complete list of retracted studies can be found on the Retraction Watch website.

Katiyar left his positions at the University of Alabama, Birmingham (UAB), and Birmingham VA Medical Center in 2017.
