Dear Margaret,
There was a 2009 systematic review of this subject published in PLOS:
How Many Scientists Fabricate and Falsify Research? A Systematic Review and Meta-Analysis of Survey Data
The authors added a rider saying that their survey results were
possibly more conservative than the real world results.
Regards,
Ash
Hello
Apologies for cross-posting
I would value advice on any reputable references which give an indication of the prevalence of recognized cases of fabrication
or falsification of data or research findings within the context of health-related
research.
Many thanks
Best wishes
Margaret
