deliberately altered before publication — an issue he
says he realized after allegations of data manipulation
surfaced online.”
▪ “…original data cited in the study is inaccessible, which
would be a contravention of the university's policy
around scientific research. ”
▪ “…the original data is in China, with an analyst who
worked on the paper.”
