What are some examples of conflicts of interest in research and how do they impact the integrity of the study?

Conflicts of interest in research can arise when researchers have financial or personal relationships that may influence their objectivity. For example, if a pharmaceutical company funds a study on a drug they produce, there may be bias towards positive results. This can impact the integrity of the study by potentially skewing the findings in favor of the sponsor's interests rather than providing unbiased and reliable information.
