“A study linking nicotine vapes to liver disease was retracted from Gastroenterology Research after the authors failed to reply to concerns about the researchers’ methods and findings. The retraction stated that “concerns have been raised regarding the article’s methodology, source data processing, including statistical analysis, and reliability of conclusions.” The study was published in June 2022. The 13 co-authors of the study drew from the National Health and Nutrition Examination Survey and analyzed participants’ responses for associations between liver disease and the use of cigarettes or vaping products. They claimed the results showed “e-cigarette users … were associated with higher odds of having liver disease compared to nonsmokers.” The data also didn’t allow for analysis around timing, which means it’s not possible to tell whether liver disease was developed before or after smoking/vaping.
“This is a greater problem than just one study,” said Gregory Conley, director of legislative and external affairs for the American Vapor Manufacturers Association, noting a 2020 retraction by the Journal of the American Heart Association of a study connecting vaping to heart attacks. The 2020 retraction letter to the journal was made public, but the issue with the Gastroenterology Research paper is less clear because “there is silence around why it was retracted,” said Conley.”
