Systematic bias favours products which are made by the company funding the research. Explanations include the selection of an inappropriate comparator to the product being investigated and publication bias (http://www.ncbi.nlm.nih.gov/pubmed/12775614)
Conflict of interest (or competing interest) statements and medline metadata describe the funding of research and potential sources of bias.
We made a tool for visualising and tracking relationships between papers and their conflict of interests.
Later we might make a simple measure, the conflict of interest index, which describes the proportion of papers for a given drug treatment, that have received industry funding or declare a conflict of interest.
