Relationship between training supervision and evolution of the density of GPs: a 3-year cohort study on French cities between 2018 and 2021.

Context: There is an uneven distribution of general practitioners (GPs) across territories of developed countries leading to inequalities in access to health care. Countries are implementing incentive or coercive policies depending on the characteristics of their health system. Several studies suggest that the location of practical training may influence the location of GPs' practices.
