ACT P&P Approved Projects 2025
Once receiving approval by the ACT P&P Committee, information about scholarly works (manuscripts, abstracts, etc.) and data requests leading to scholarly works is shared to facilitate collaboration on active ongoing projects and to reduce potential duplication of research on the ACT cohort. Approved projects are catalogued in searchable tables by year.
Approved data requests and manuscript proposals initiate the formation of writing groups of co-authors. Interested researchers may nominate themselves or a qualified colleague to participate in a writing group by contacting the lead directly. Writing group nominations should occur within the one month following P&P approval.
Approved final draft manuscripts and abstracts are shared for informational purposes. Researchers who are interested in working with ACT data can locate research in the process of being submitted for publication. Once published, manuscripts and abstracts may be found in the ACT Publication Database.
