Experimental Design

Research transparency is a term used to describe the sharing and dissemination of research and research outcomes. It is considered good ethical practice to share research in an open and transparent way, both within the scientific community and with the wider public.
Research transparency requires that the methods, experimental design, data, analysis, evidence and conclusions from research are comprehensively reported and disseminated openly (and ideally free of charge). In scientific research, progress is often made in incremental steps building on work that has gone before. The sharing of research is therefore important not only within the scientific community but also within the public domain.
Transparency is considered a key aspect of ethical research practice and it is important for many reasons:
In the current system research is shared through the publication of papers in scientific journals. These can be published open-access (available to everyone, for free), or in closed-access journals where only those with a subscription can view the papers. Whilst these papers cannot then be published elsewhere due to copyright issues, a short abstract of the paper can be shared and searched for, and a payment is made to the publisher to receive the full article. Cost can sometimes impact transparency, as publishing a paper open access often costs an author significantly more, whereas in the traditional, paywalled publication model, the cost is charged to the reader.
Clinical trials are studies that require people to be used to assess the outcomes of a health-related intervention, such as assessing the safety or efficacy of a potential new drug. Clinical trials are now required to be added to a public register before they are carried out. This requirement was introduced to counteract the distortion of scientific evidence that happens as a result of unsuccessful trials (those where there were no clinical benefits or negative/null results) not being published or therefore shared. As mentioned earlier, knowledge can be gained from negative results as well as positive – it is critical to funding and policy decisions to know what doesn’t work as well as what does. Although the current system for registering clinical trials may not always be fast or efficient, it helps improve transparency in medical research.
Animals are used in many preclinical trials (early drug development studies to evaluate efficacy and safety) and there is no requirement currently to publicly register or share outcomes of unpublished animal research. As with clinical trials, this lack of transparency inhibits scientific progress by allowing a range of poor practices to potentially continue unseen and means that valid negative outcomes often remain invisible. It is also a significant ethical issue with animal lives being wasted repeating research that has already been conducted.
When research is not published, that research cannot easily be searched for, seen, scrutinised, or used to inform other studies.
There are some systems in place to address this to increase transparency, although they are not compulsory, or widely used.
Ultimately encouraging transparency in animal research will help build the evidence base to understand and challenge the usefulness of animal studies in different areas and replace it with approaches that offer more scientifically and ethically robust solutions. To this we need to strengthen and improve current systems that increase transparency in animal research and give the researchers the tools and confidence to use these systems and without abuse.

Research findings are “reproducible” if a study can be independently carried out using the same methods to obtain the same data and results. If research is reproducible, it is more likely that the results are valid and therefore correct.
If research is transparent and contains all the necessary detail in the publication about how the study was conducted, it is easier to establish whether it is reproducible. Sadly, there are examples of published research, accepted by peer-reviewed journals that are not reproducible. Common causes of problems with reproducibility are the implementation of poor experimental design in a research study and poor reporting of studies both of which make it difficult to accurately repeat the study and obtain the same results.
Reproducibility is a particular concern in studies that use animals. Scientific research that is not reproducible is generally considered to be of little or no value as it cannot be carried out again or ‘reproduced’. There is an ethical issue here where animals have been used as the lack of reproducibility may have been caused by an avoidable failure in study design or reporting. There is then also a risk of repeated studies in the same area to correct design flaws and attempt to identify valid conclusions, or if the lack of reproducibility is not picked up, to ask slightly different research questions based on the initial flawed results.
