Corporate sponsored META-ANALYSES are more
likely to be favorable than independent papers.
• Corporate sponsored meta-analyses
5.1 (OR 1.5 - 16.9) times more likely to
report favorable conclusions.
– BMJ 2007;335:1202-05 124 meta-analysis, (40% supported
by a drug company), multivariate, (regression analysis)
Meta-analysis: the statistical compilation of
several studies for finding out their larger
conclusion. (Glass, 1976)
Publication Bias & Sponsored Studies
• When results are positive, sponsors more
likely to publish multiple papers on
preliminary and final results.
– BMJ 2003;326:1171-6. (42 studies)
• Duplicate publication of the same studies
resulted in meta-analyses overstating
ondansetron’s antiemetic efficacy by 23%.
– BMJ 1997;315:635-40.
Corporate Ghostwriters
• 75% in industry-sponsored trials
– JAMA 2008;299 1800-12. See also JAMA 1998;280:222-24.
• Orthopedic Devices
– Of 32 authors receiving more than $1 Million from five
orthopedic companies, 46% disclosed their support
even when writing on the company product.
– Arch Int Med 2010;Sept 13 online first.
• Refoxecoxib (Vioxx)
– 50% (36/72) of review ghost authors disclosed
support.
– JAMA 2008;299-1800-12.
Corporate Ghostwriters
• Wyeth paid Excerpta Medical (medical communications
company) $200,000 for 10 articles.
–“I was given explicit instructions about what to play up and what
to play down—whether to enhance broader off-label use of the
pain product or go strictly by the FDA.” –RS
–“I was given a list of drug company approved phrases. I was
pressured to revise my drafts to position the product more
favorably.“ –ML Lancet 1999;354:136.
• After controlling for size of benefit, sponsored papers 5.3 X
more likely to say corporate drug is “drug of choice.”
– JAMA 2003;290:921-928. 370 RCTs from a random sample of 167
Cochrane reviews.
Favorable trials are published. Negative trials are not.
Some companies present negative studies as positive.
51% of registered trials
(published and not published)
were favorable to the product.
• 94% of the registered trials that
were published were favorable.
• Publication bias increased
apparent efficacy by 32%, range
11-69% for individual drugs.
