Dartmouth’s Steve Woloshin and Lisa Schwartz have studied the pitfalls of news coverage based on scientific meetings. Their new work, in the Medical Journal of Australia, looked at print and broadcast news stories based on research reports at five major scientific meetings on heart disease, AIDS, cancer, neuroscience and radiology.
Results: “34% of the 187 stories did not mention study size, 18% did not mention study design (another 35% were so ambiguous that expert readers had to guess the design), and 40% did not quantify the main result. Only 6% of news stories about animal studies mentioned their limited relevance to human health; 21% of stories about small studies noted problems with the precision of the finding; 10% of stories about uncontrolled studies noted it was not possible to know if the outcome really related to the exposure; and 19% of stories about controlled but not randomised studies raised the possibility of confounding. Only 29% of the 142 news stories on intervention studies noted the possibility of any potential downside. Twelve stories mentioned a corresponding ‘in press’ medical journal article; two of the remaining 175 noted that findings were unpublished, might not have undergone peer review, or might change.”
This is important work, pointing out that “the public may be misled about the validity and relevance of the science presented.”

The tale of two “negative” studies. Or, how spin is applied to make research findings look more impressive. A must read. https://johnmandrola.substack.com/p/the-tale-of-two-negative-studies
The @nytimes chose to interview one of the editors of the @AnnalsofIM (publisher of this paper) who "gushed with extraordinary glee: It’s huge! There are very few things that reduce your mortality by 30%."
Turns out coffee is not one of those few things despite all that glee. https://twitter.com/garyschwitzer/status/1533202075928215558

We will delete comments that include personal attacks, unfounded allegations, unverified claims, product pitches, profanity or any from anyone who does not list a full name and a functioning email address.

We don”t have sufficient staffing to contact each commenter who left such a message. If you have a question about why your comment was edited or removed, you can email us at feedback@healthnewsreview.org.
There has been a recent burst of attention to troubles with many comments left on science and science news/communication websites. Read “Online science comments: trolls, trash and treasure.”
The authors of the Retraction Watch comments policy urge commenters:
We”re also concerned about anonymous comments. We ask that all commenters leave their full name and provide an actual email address in case we feel we need to contact them. We may delete any comment left by someone who does not leave their name and a legitimate email address.
And, as noted, product pitches of any sort – pushing treatments, tests, products, procedures, physicians, medical centers, books, websites – are likely to be deleted. We don”t accept advertising on this site and are not going to give it away free.
