Most scientific papers are probably wrong

Most published scientific research papers are wrong, according to a new analysis. Assuming that the new paper is itself correct, problems with experimental and statistical methods mean that there is less than a 50% chance that the results of any randomly chosen scientific paper are true.

John Ioannidis, an epidemiologist at the University of Ioannina School of Medicine in Greece, says that small sample sizes, poor study design, researcher bias, and selective reporting and other problems combine to make most research findings false. But even large, well-designed studies are not always right, meaning that scientists and the public have to be wary of reported findings.

"We should accept that most research findings will be refuted. Some will be replicated and validated. The replication process is more important than the first discovery," Ioannidis says.

In the paper, Ioannidis does not show that any particular findings are false. Instead, he shows statistically how the many obstacles to getting research findings right combine to make most published research wrong.

Massaged conclusions
Traditionally a study is said to be "statistically significant" if the odds are only 1 in 20 that the result could be pure chance. But in a complicated field where there are many potential hypotheses to sift through - such as whether a particular gene influences a particular disease - it is easy to reach false conclusions using this standard. If you test 20 false hypotheses, one of them is likely to show up as true, on average.

Odds get even worse for studies that are too small, studies that find small effects (for example, a drug that works for only 10% of patients), or studies where the protocol and endpoints are poorly defined, allowing researchers to massage their conclusions after the fact.

Surprisingly, Ioannidis says another predictor of false findings is if a field is "hot", with many teams feeling pressure to beat the others to statistically significant findings.

But Solomon Snyder, senior editor at the Proceedings of the National Academy of Sciences, and a neuroscientist at Johns Hopkins Medical School in Baltimore, US, says most working scientists understand the limitations of published research.

"When I read the literature, I'm not reading it to find proof like a textbook. I'm reading to get ideas. So even if something is wrong with the paper, if they have the kernel of a novel idea, that's something to think about," he says.

Panelists in FDA Drug Vote Tied to Makers
Yahoo (AP prss release) ^ | Feb 25, 4:03 PM

A study by the Center for Science in the Public Interest indicates that 10 of the 32 panel members had ties to either Pfizer Inc. or Merck & Co., ranging from consulting fees and speaking honoraria to research support.

The FDA issued a statement saying it screened members of the panel for conflicts of interest. "This transparent process requires the agency to carefully weigh any potential financial interest with the need for essential scientific expertise in order to protect and advance the public health," the agency said.

After three days of hearings on the drugs, known as Cox-2 inhibitors, the panel voted 31-1 to keep Pfizer's Celebrex on the market, 17-13 with 2 abstentions in favor of Pfizer's Bextra and 17-15 that Merck's Vioxx should be allowed back on sale.

Merck pulled Vioxx from the market Sept. 30 after heart problems were reported in some users. Similar questions were later raised about the other two drugs, prompting the FDA to call the advisory panel to look into the matter.

Since drug companies fund many studies it is not unusual for researchers to have ties to manufacturers, though some have questioned the practice.

The transcript, including the votes by the individual members of the panel, has not yet been posted by the FDA. However, a copy obtained by The Associated Press indicated that the 10 panel members in question voted 10-0 in favor of keeping Celebrex and Bextra available and 9-1 in favor of allowing Vioxx to be brought back onto the market.

Without those ballots the vote would have been 13-7 in favor of withdrawing Bextra and 14-8 to keep Vioxx off sale.

The industry ties of the panel members were first reported Friday by The New York Times.

Documents Said to Show Prozac Risks
NY Times ^ | December 31, 2004 | REUTERS

LONDON, Friday, Dec. 31 (Reuters) - The British Medical Journal said on Friday it had sent documents to health regulators in the United States that it said appear to suggest a link between the antidepressant drug Prozac and suicidal behavior.

The journal said an anonymous source had provided "missing documents" relating to clinical trials of the drug, made by Eli Lilly & Company.

It said the documents had been lost during a product liability suit in 1994. They included reviews and memos that appeared to show Eli Lilly officials were aware in the 1980's that the drug, whose generic name is fluoxetine, had "troubling side effects," the journal said.

Officials at Eli Lilly, which is based in Indianapolis, could not immediately be reached for comment on the report.

In an article appearing in its Jan. 1 issue, which it posted on its Web site at www.bmj.com on Friday, the journal said it had sent the papers to the Food and Drug Administration.

It quoted Dr. Richard Kapit of the F.D.A., a clinical reviewer who approved fluoxetine, as saying that he had not been given the data highlighted in the documents, and that they were "very important."

The journal said Lilly officials declined to be interviewed but issued a statement saying the safety and usefulness of Prozac were well established.

Traumatized Kerry supporters in Florida seek therapy: report

MIAMI (AFP) Nov. 9, 2004- Shocked supporters of defeated US presidential candidate John Kerry are seeking help from psychologists, who refer to their condition as "post-election selection trauma."

The Boca Raton News reported Tuesday that Palm Beach, Florida trauma specialist Douglas Schooler alone has already treated 15 clients and friends with intense hypnotherapy since the Democratic candidate conceded on November 3.

"I had one friend tell me he's never been so depressed and angry in his life," Schooler said. "I observed patients threatening to leave the country or staring listlessly into space. They were emotionally paralyzed, shocked and devastated," he told the daily.

"We're calling it 'post-election selection trauma' and we're working to develop a counseling program for it," said Rob Gordon, the Boca Raton-based executive director of the American Health Association.

"It's like post-traumatic stress syndrome, but it's a short-term shock rather than a childhood trauma," he told the daily.

Kerry supporters seek therapy in South Florida
Boca Raton trauma specialist has treated 15 patients
Boca Raton News Tuesday, November 9, 2004 1:00 am
by Sean Salai

More than a dozen traumatized John Kerry supporters have sought and received therapy from a licensed Florida psychologist since their candidate lost to President Bush, the Boca Raton News learned Monday.
Boca Raton trauma specialist Douglas Schooler said he has treated 15 clients and friends with “intense hypnotherapy” since the Democratic nominee conceded last Wednesday.
“I had one friend tell me he’s never been so depressed and angry in his life,” Schooler said. “I observed patients threatening to leave the country or staring listlessly into space. They were emotionally paralyzed, shocked and devastated.”
Schooler’s disclosure comes after the weekend discovery of a Kerry volunteer’s corpse at Ground Zero in New York City. Georgia resident Andrew Veal, 25, reportedly killed himself with a shotgun blast to the head due to Kerry’s loss and a girlfriend problem.
Some mental health professionals in South Florida said Monday they have already developed a new category for the Kerry-related stress reactions. Because Palm Beach County voted heavily for Kerry, the therapists said, many residents hurt themselves by so anxiously expecting the Massachusetts senator to win – especially those who maintained unrealistic recount hopes after their candidate’s concession.
“We’re calling it ‘post-election selection trauma’ and we’re working to develop a counseling program for it,” said Rob Gordon, the Boca-based executive director of the American Health Association. “It’s like post-traumatic stress syndrome, but it’s a short-term shock rather than a childhood trauma.”
Gordon, the first American Red Cross psychotherapist sent to Ground Zero after the 9/11 terror attacks, said therapists’ main concern is to prevent the recurrence of Kerry-related suicides like the one in New York City.
“There are definitely people depressed by John Kerry’s loss, and this can easily lead to suicides like the one we saw up in New York this weekend,” Gordon said. “Luckily, it can be treated if people seek help. We’re urging people to call us immediately if they feel depressed or know anyone who is seriously stressed out.”
Also in Boca, at least one counseling center and an emotional support group were preparing for an influx of Kerry supporters at their first post-election meetings today.
“We’ll let the Kerry voters talk about it and let off some steam, and by listening to other people’s stories, we’ll help them refocus and surrender to the things in their life which they can’t possibly change,” said a spokeswoman for Emotions Anonymous, a recovery group meeting tonight at Glades Presbyterian Church.
“We’re referring people with election-related stress to the Democratic National Committee,” said Karen Jacobs of the Center for Group Counseling. “We’ll do what we can for anyone who shows up for our support group programs this week, but we haven’t implemented a specific program for Kerry-related trauma.”
Schooler, practicing in Boca since 1984, said he treated his 15 patients last week with hypnosis-based rapid response trauma therapy. This week, he is charging a sliding fee to non-clients who feel they need the one-time “election therapy” session. South Floridians can contact him at 561-395-3033.
“A lot of Kerry voters don’t know what to do with their anger, because there was no recount, so they’ve kept it bottled up,” said Schooler, who also is a certified sex therapist. “I help them transform the anger into more positive emotions.”
Asked to describe symptoms of the post-election trauma, Schooler said, “They include feelings of extreme anger, despair, hopelessness, powerlessness, a failure to function behaviorally, a sense of disillusionment, of not wanting to vote anymore – that sort of thing. We’re talking about a deep, unhealthy personal suffering that can best be remedied by intensive short-term therapy.”
