In an official statement, the editors of the Journal of the American Heart Association (JAHA) explained why they retracted a study claiming that e-cigarettes increase the likelihood of having a heart attack.
The now-retracted study by two University of California at San Francisco researchers, published in JAHA last year, claimed they had found an "association between e‐cigarette use and having had a myocardial infarction." They concluded that the "effect of e‐cigarettes are similar as conventional cigarette and dual use of e‐cigarettes and conventional cigarettes at the same time is risker [sic] than using either product alone."
But tobacco control expert Brad Rodu, from the University of Louisville, discovered that the study had a major fault: Many of those analyzed for the study were also current or former smokers, as Vice reports.
That reality likely skewed their findings, according to Rodu — an argument later backed up by several senior researchers in an open letter, in which they argued that a conclusion that's "not supported by underlying data" could "mislead practitioners and policymakers."
"A retraction is not a trivial matter," Rodu told Vice. "It's a significant action. Saying it was a mistake is too weak."
On Twitter, though, paper author Stanton Glanz shot back, claiming that JAHA had given in to "pressure from e-cig interests."
