Conclusion
This study demonstrated that more than half of all endocrinologists accepted at least one GPEOR from the healthcare industry in the US each year, but only a few received substantial GPEOR. However, GPEOR had been decreasing annually since the inception of the Open Payments Database. The majority of industry payments were made to the small number of endocrinologists for research expenses individually or mostly through their institutions.
