Heart study bleeds into three papers, one retracted and one withdrawn

janWith the increasingly hectic pace of modern life, everybody is always on the look out for time-saving tricks and tips.

Scientists at the National University of Singapore and the Hong Kong Polytechnic University certainly found one, but we really can’t recommend it: doing one randomized controlled trial (RCT) with several outcomes, and publishing them as three separate 2014 papers with “considerable overlap.”

So far, one paper has been retracted, and another withdrawn.

Cardiac arrestees: Questions surface about Heart paper from Italian group that faces charges

heartcoverWe don’t usually cover “pretractions” (see #5 for why), but our friend Larry Husten over at Forbes has a story today about what appears to be a dead paper walking.

The article, in Heart, comes from a group of prominent researchers in Italy who have been arrested for possibly failing to adequately consent their patients, among other potential misdeeds.

According to Husten, the 2010 article in question, “A randomised trial of target-vessel versus multi-vessel revascularisation in ST-elevation myocardial infarction: major adverse cardiac events during long-term follow-up,” by Maria Grazia Modena (a past president of the Italian Society of Cardiology) and colleagues, may have been grossly misrepresented to the journal.

Heart pulls sodium meta-analysis over duplicated, and now missing, data

heart cover may13The journal Heart has retracted a 2012 meta-analysis after learning that two of the six studies included in the review contained duplicated data.  Those studies, it so happens, were conducted by one of the co-authors.

The article, “Low sodium versus normal sodium diets in systolic heart failure: systematic review and meta-analysis,” came from an eclectic group of authors from the United States, Canada and Italy (the first author is listed as being at a Wegmans pharmacy in Ithaca, N.Y.). The paper, published online in August 2012, purported to find that: Continue reading Heart pulls sodium meta-analysis over duplicated, and now missing, data

Heart retracts stent-ReoPro paper over data dispute with authors (save one)

We’re a few months late on this one, but Heart, a BMJ title, issued a fascinating retraction notice in August about a meta-analysis on percutaneous coronary intervention (that’s stenting to you and me) after suffering a heart attack, and the drug abciximab, which is used to prevent clotting and additional near-term heart attacks. Abciximab is sold as ReoPro by Eli Lilly.

The article, “Clinical impact of intracoronary abciximab in patients undergoing primary percutaneous coronary intervention: an individual patient-data pooled analysis of randomised studies,” was published last May. But according to the retraction notice, the authors had neglected to include fresh data, already in the literature before their paper went live, that contradicted their overall findings.

Here’s the notice: Continue reading Heart retracts stent-ReoPro paper over data dispute with authors (save one)

Heart study pulled after production glitch leads to duplicate publication

On reflection, that headline pretty much says it all. But for those readers who took the time to click on the link, here’s the rest of it.

The journal Heart, a title of the BMJ group, has retracted a paper that it published twice: Continue reading Heart study pulled after production glitch leads to duplicate publication
