Explanation:

If you are interested in forming a group of medical providers to participate in a research, it is likely that this group will be formed based on the expertise of medical providers. Thus the research would be done in a comprehensive way, where each member of the group would use their expertise to deal with the research in the best way possible and promote, through the research, an improvement for the population's health.

In addition, medical providers with the same specialty will make the research deeper and richer.
