A JAMA journal has retracted a paper on vaping it published two months ago after the researchers alerted the editors to “significant coding errors” and other problems with the work. 

The article, “Efficacy of Electronic Cigarettes vs Varenicline and Nicotine Chewing Gum as an Aid to Stop Smoking: A Randomized Clinical Trial,” was written by a group from China led by Zhao Liu, of the Department of Tobacco Control and Prevention of Respiratory Disease at China-Japan Friendship Hospital, in Beijing. 

According to the researchers, the study found use of vapes was no worse than a prescription medication, and better than nicotine gum, at helping people quit smoking. 

The paper received a significant amount of attention in the medical and lay press and on social media (full disclosure: Medscape, where Adam works, covered it). 

Here’s the March 29 retraction notice for the paper, which originally appeared online in JAMA Internal Medicine January 29:

Are academic writing centers agents of US hegemony, spreading the evils of colonialism as they work to topple rogue syntax and rehabilitate failing grammatical states?  

So argued a pair of authors in Canada in a now-retracted 2022 article which claimed that such centers have been used as “neocolonial tools” to push American foreign policy goals. 

But according to critics, that claim –  which seems like it might have emerged from a cross between Don DeLillo’s “White Noise” and Graham Greene’s, well, lots of his books – suffered from a fatal flaw or two, as we’ll shortly see.

A pair of researchers in New Zealand have asked for the retraction of a controversial article on the risk of miscarriage in pregnant women who receive a vaccination against Covid-19, according to one of the co-authors.

Simon Thornley, of the University of Auckland — and an outspoken critic of New Zealand’s efforts to contain the Covid-19 pandemic — and Aleisha Brock, of Whanganui, N.Z., published a reanalysis of a study in which they claimed to have found that as many as 91% of pregnant women miscarry after receiving a Covid jab. 

But after an onslaught of criticism — including a scathing email from an official at the University of Auckland — Thornley tells us he and Brock have decided to retract their paper, although he declined to tell us why.

A journal has retracted a 2018 paper that linked negative news coverage to physical and mental health problems.

The article, “When Words Hurt: Affective Word Use in Daily News Coverage Impacts Mental Health,” was published in Frontiers in Psychology in August 2018. The study has been cited six times, according to Clarivate Analytics’ Web of Science. In March 2020, an article in The Conversation used the study’s findings to argue that kids should reduce their television intake during the coronavirus pandemic to ward off anxiety.

First author Jolie Wormwood, an assistant professor of psychology at the University of New Hampshire, said she decided to pull the study after revisiting the dataset. She found that some of the study participants—95 people in the Boston area—who completed a questionnaire three different times during a nine month period, gave inconsistent answers about their memory of an event. That normally might not be too worrying, since memories “shift over time”, according to Wormwood, but a bit more sleuthing revealed that the researchers had inadvertently mixed up the IDs that were assigned to study participants.

Wormwood explained the error in an email:
