"Partiality can arise when pressure is brought to bear on the researcher by any parties that have an interest in seeing the research results favor their particular interests."

"Epidemiologists should not enter into contractual obligations that are contingent upon reaching particular conclusions from a proposed study."

"Although epidemiologists cannot always prevent the media or other parties from sensationalizing research results, epidemiologists should strive to ensure that, at a minimum, research findings are interpreted and reported on accurately and appropriately."
