The probability of replicating ‘true’ findings is low…

coinflipDue to small group sizes and presence of substantial bias experimental medicine produces a  large number of false positive results (see previous post). It has been claimed that 50 – 90 % of all results may be false (see previous post). In support of these claims is the staggerlingly low number of experiments that can be replicated. But what are the chances to reproduce a finding that is actually true?

Is more than 80% of medical research waste?

The Lwasteancet has published a landmark series of 5 papers on quality problems in biomedical research, which also propose a number of measures to increase value and reduce waste. Here is our commentary and summary . All articles are freely available on the internet (rather unusual for an Elsevier journal…).

From the Lancet pages:

The Lancet presents a Series of five papers about research. In the first report Iain Chalmers et al discuss how decisions about which research to fund should be based on issues relevant to users of research. Next, John Ioannidis et al consider improvements in the appropriateness of research design, methods, and analysis. Rustam Al-Shahi Salman et al then turn to issues of efficient research regulation and management. Next, An-Wen Chan et al examine the role of fully accessible research information. Finally, Paul Glasziou et al discuss the importance of unbiased and usable research reports. These papers set out some of the most pressing issues, recommend how to increase value and reduce waste in biomedical research, and propose metrics for stakeholders to monitor the implementation of these recommendations.

How Science goes wrong

How science goes wrong Economist Cover 19.10.2013Scepticism regarding the quality and predictiveness of modern science has finally arrived in the lay press. This week The Economist has devoted its issue, including, cover, editorial, and leader to what they call ‘unreliable research’. Even closer to home, this weeks New Scientist (also with cover, editorial and leader) turns on neuroscience, with a similar message and material, and the bottom line that ‘the vast majority of brain research is now drowning in uncertainty.’ A clear signal that it is either time to abandon ship, or to clean up the mess!

 

 

Call for international collaboration in preclinical research

maus auf schlafendem mannTranslational stroke medicine requires renewal, and international collaboration in preclinical research may be an important step to overcome hurdles impeding progress. The tremendous power of international research collaboration has been convincingly demonstrated in physics, and several transnational collaborations have already delivered proof of concept in the stroke field. The experience gleaned from such collaborations is paving the way for an exciting new era in stroke research, which strives to harness the multitude of benefits achievable through international collaboration. Now is the time for concrete action to advance the agenda and establish an international preclinical stroke network (click here for full article:  Concerted Appeal for International Collaboration Stroke 2013)-
