How Pharmaceutical Companies are able to manipulate studies in their favor

This Is The Sickening Amount Pharmaceutical Companies Pay Top Journal Editors

12 APRIL 2018

It's no secret that scientists can be corrupted - in the past, researchers have purposefully hidden data on climate change, and the dangers of sugar, just to name a few.

But while people can be bought, the scientific method itself - the idea that a hypothesis must be observed, tested, replicated, and the results then published in a peer-reviewed journal - has always remained a beacon of objectivity, assumedly free of bias by its very nature.

Unfortunately, in recent years scientific publishing has been running into serious trouble.

Through predatory journals, publication bias, and a publish-or-perish mentality, the way we practice the scientific method has been corrupted right under our noses - we're at a point now where some studies can't even be reproduced.

More recently, it's become clear that the system for publishing results on evidence-based medicine is broken, too.

On paper, evidence-based medicine is a good thing. It's how we get life-saving treatments and medication, and it's the requirement for any new drugs to be based on solid, peer-reviewed research.

But this assumes that peer-reviewed research will be unbiased, and that's not always the case.

Just last week, a report concluded that many clinical trials are greenlit based on a shockingly poor evidence base, sometimes without any published data.

Now nephrologist Jason Fung has taken to Medium to highlight even more damning evidence against the journals we rely on to print the best academic research.

His article is a summary of information that's already out there, published in the lead up to a presentation to the European Parliament this week. But seeing it all in one place is confronting.

Most shocking: medical journal editors are paid huge sums by pharmaceutical companies each year.

This is something most of us already know - we see the sponsored pens and all the fancy conferences doctors go on thanks to 'big pharma'.

But that's only a small part of it. The industry also just hands them money directly.

A paper published last year in the British Medical Journal examined how much money editors of the world's most influential medical journals were taking from industry sources.

Of the journals that could be assessed, 50.6 percent of editors were receiving money from the pharmaceutical industry - in some cases, hundreds of thousands of dollars.

Here's just a small highlight showing editor payments received in 2014 - the amount on the left is direct payments, and the 'research' payments on the right are less regulated, usually made in the form of expensive research trips. 

0 pZfQ9GoITCWVINWE 1(Liu et al., BMJ, 2018)

The average 'in hand' payment in 2014 alone was US$27,564, plus research funds. 

Worst on that list is the Journal of the American College of Cardiology (JACC), where 19 of its editors received, on average, US$475,072 personally and another US$119,407 for 'research'.

And that's not even mentioning the amount of reprint money journals get whenever they publish a study that supports a pharmaceutical company, and the company pays for hundreds of copies to send out to doctors.

The Lancet earns 41 percent of its income from reprints, and the American Medical Association gets 53 percent.

"The medical profession is being bought by the pharmaceutical industry, not only in terms of the practice of medicine, but also in terms of teaching and research," said the late Arnold Relman, a former editor-in-chief of the New England Journal of Medicine (NEJM) in 2002. He passed away in 2014.

"The academic institutions of this country are allowing themselves to be the paid agents of the pharmaceutical industry. I think it's disgraceful."

Why does all this matter? In the face of these kind of numbers it's easy to see why journal editors would choose to print research that supports products of these companies, and ignore the evidence that goes against them.

And that's exactly what's happening.

Research backed by the pharmaceutical industry is far more likely to have positive results published than government-funded science.

Not only that, but negative results are often ignored. In a 2008 study that Fung cites, 36 out of 37 studies that were favourable to antidepressants were published.

In comparison, only 3 out of 36 studies that were not favourable to the drugs made it to print.

That means if you were to solely look at the published literature, you would think an overwhelming 94 percent of studies show these antidepressants work, when, in reality, only 51 percent of the studies conducted were actually positive.

Seeing these numbers in black and white is sobering.

Despite grumbles of 'big pharma', most of us still put our faith in the peer-review process, confident that the scientific method will guide us in the right direction regardless of people's own bias.

Unfortunately, the results provided to us by the scientific method are only as good as the editors that gatekeep them. 

This is why more and more researchers are publishing their work in pre-print and open-access journals, where the world can see their research for free.

There's also a push to get organisations to publish all valid results, even if they're negative.

We have a long way to go, but it's only by acknowledging a system is broken that we can begin to fix it.

Big Sugar Buried These Concerning Health Studies 50 Years Ago

HILARY BRUECK, BUSINESS INSIDER
22 NOVEMBER 2017

New evidence shows the sugar industry suppressed scientific research that linked sugar to heart disease and bladder cancer in rats.

The Sugar Research Foundation, the group funding the studies, cut the project short and didn't publish the results. Nutritionists caution that sugar, not fat, is largely to blame for many of the problems in our modern diets.

For decades, sugar lobbyists have been taking aim at studies linking sugar and cancer.

When a study last year found that mice on sugar-heavy diets were more likely to develop breast cancer, the Sugar Association – one of the biggest sugar lobbying groups in the US – called it "sensationalised." The group insists that "no credible link between ingested sugars and cancer has been established."

But doctors and researchers claim the sugar industry may have been intentionally keeping research about that link from getting published.

A new study in the journal PLOS Biology reveals how the Sugar Association worked to suppress scientific findings on the harmful effects of table sugar on rodents nearly 50 years ago.

The report details the results of two unpublished studies, known as Project 259, which were funded by the sugar lobby in the late 1960s. Both involved research on the effects of feeding sugar to rats.

In the first study, one group of rats was fed a balanced diet of cereal, beans, fish and yeast, while the other rats were given a high-sugar diet.

The researchers found that the sugar eaters were at greater risk for strokes, heart attacks and heart disease, and had higher-than-normal levels of fat (triglycerides) in their blood.

The second study compared sugar-fed rats with starch-fed rats and found that the sugar-eating rodents were more likely to have elevated levels of an enzyme associated with bladder cancer in humans.

None of that rodent research saw the light of day, though. The Sugar Research Foundation cut Project 259 short and didn't publish any of the results.

"Our study contributes to a wider body of literature documenting industry manipulation of science," the researchers, who hail from the University of California San Francisco, wrote in their report.

In a statement, the Sugar Association denied that allegation, saying the new study is just "a collection of speculations and assumptions about events that happened nearly five decades ago, conducted by a group of researchers and funded by individuals and organisations that are known critics of the sugar industry."

"We reviewed our research archives and found documentation that the study in question ended for three reasons, none of which involved potential research findings: the study was significantly delayed; it was consequently over budget; and the delay overlapped with an organisational restructuring," the group said.

But this is not the first time we've learned that 'big sugar' has gotten in the way of science.

Last year, some of the same researchers found that the Sugar Research Foundation – the former name of the Sugar Association – paid off three Harvard scientists in 1967 to make sugar seem less unhealthy and suggest that fat was the problem in our diets instead.

"The kind of manipulation of research is similar to what the tobacco industry does," study co-author Stanton Glantz said in a release.

Decades of research on sugar since Project 259 have linked sugar consumption to a glut of serious health problems, including high cholesterol, heart disease, and kidney disease, to name a few.

Recent research also suggests that sugar may play a role in tumour growth, but scientists don't think it makes cancer grow faster, and still aren't certain whether sugar consumption has any link to cancer formation.

After years of fuelling up on high-sugar, low fat foods, consumers are finally becoming wise to the problems with sugar that were hidden for so many years.

And the US Food and Drug Administration is, too – by 2021, all nutrition labels will have to include the per cent daily value of added sugars for the first time, while the "calories from fat" column will get scrubbed.
