[On April 8th] at the University of California at Los Angeles, a rally [was] planned to raise awareness about the value of responsible animal research and to denounce acts of terrorism toward animal researchers and their families. The highlight of the “Pro-Test” rally [was] the presentation to legislators and the media a petition with nearly 12,000 signatures of scientists who support the use of animals in research.
The rally and the petition drive [was] a joint effort of Americans for Medical Progress, Pro-Test for Science, and Speaking of Research.
I stand together with my colleagues who conduct animal research in honor of their application of knowledge to advance biology and relieve human suffering, all while a growing movement of animal rights activists up the ante from protests to attacks on researchers, destruction of homes by arson, and even the vandalism of graves of researchers’ loved ones.

A new study published in PLOS Biology looks at the potential magnitude and effect of publication bias in animal trials. Essentially, the authors conclude that there is a significant file drawer effect –- failure to publish negative studies -– with animal studies and this impacts the translation of animal research to human clinical trials.
SBM is greatly concerned with the technology of medical science. On one level, the methods of individual studies need to be closely analyzed for rigor and bias. But we also go to great pains to dispel the myth that individual studies can tell us much about the practice of medicine.
Reliable conclusions come from interpreting the literature as a whole, and not just individual studies. Further, the whole of the literature is greater than the sum of individual studies –- there are patterns and effects in the literature itself that need to be considered.
One big effect is the file drawer effect, or publication bias –- the tendency to publish positive studies more than negative studies. A study showing that a treatment works or has potential is often seen as doing more for the reputation of a journal and the careers of the scientists than negative studies. So studies with no measurable effect tend to languish unpublished. Read more »
