The Dialysis Outcomes and Practice Patterns Study (DOPPS) has a long history of successful collaborations with investigators outside of Arbor Research Collaborative for Health. We are committed to collaboration with external investigators to maximize the scientific value of the wealth of data made possible by all the participating facilities and patients. To continue our tradition of providing unique opportunities for scientific investigation, we invite interested researchers to learn more about opportunities for collaboration with us.
