Have a research question? Start by reading the NA-ACCORD’s Collaboration Polices and overview of the steps required in our proposal development process. Then, review our list of Available Data elements, to ensure your research question can be addressed with these data. After this, complete the NA-ACCORD Concept Sheet to submit your idea for approval. If you prefer to be sent the data, this will require approval from your local Institutional Review Board. If you are interested in requesting analytic assistance from the Epidemiology/Biostatistics Core please contact Aimee Freeman ([email protected]). The concept sheet approval process is explained below.​
