Investigators interested in performing AAST-sponsored multi-center studies contact the Chair of AAST-MIT to discuss the idea. A protocol and data collection sheet is requested. These documents are circulated among the members of the AAST-MIT and revisions are suggested or approval is granted. The process is rapid and typically will not exceed one month. As soon as the study is approved for AAST sponsorship, the protocol and data collection sheet are included in this webpage. Interested centers can participate after they complete the simple Participating Center Information form.
