A false hyperlink between e-cigarettes and coronary heart assaults

The newspaper of the
The American Coronary heart Affiliation of June 5, 2019 printed an article,
"Use of the digital cigarette and myocardial infarction in American adults
Analysis of the tobacco inhabitants and well being [PATH], "By Dharma N. Bhatta and
Stanton A. Glantz (right here). Studying the article, I found that the
the authors misrepresented the analysis file; introduced a grossly inaccurate evaluation of
Wave 1 survey information from PATH, and important data omitted concerning (a)
when the survey contributors first realized that that they had a coronary heart assault, and (b)
when contributors began utilizing digital cigarettes. The article mirrored a major departure
accepted analysis practices.

The authors identified that present customers of digital cigarettes have been
twice as possible as ever customers to have had a coronary heart assault, primarily based on data
of 38 contributors within the survey. They
reported odds ratio (OR) of two.25 (95% confidence interval, CI = 1.23 – four.11)
for 19 each day vapers and 1.99 (CI = 1.11 – three.58) for 19 each day customers
(Abstract, Desk three and Desk S6). Drs. Bhatta
and Glantz said that their examine confirmed that "the usage of the e-cigarette is a
unbiased danger issue for having a myocardial infarction … ". In a weblog publish concerning the College of
Dr. Glantz cited the examine as "extra proof than
that e-cigs trigger coronary heart assaults "(right here).

I’ve in depth expertise in PATH analysis
information recordsdata. I did an evaluation of
public use of Wave 1 information, which has no restrictions on the dissemination of
outcomes. I discovered that at the least 11 of the present 38
It was first instructed to the customers of digital cigarettes that that they had had a coronary heart assault years earlier than
they began utilizing digital cigarettes.

My analysis workforce carried out different analyzes that have been
mentioned within the letters we despatched to JAHA
editors-in-chief July 11th and 18th; these letters have by no means been acknowledged. On the instruction of the interuniversity
Consortium for Social and Political Analysis, I’m not in a position to share these
letters with you.
