Study Results

Now is the time to learn about findings from nearly a decade of research.

Anyone can sign up to receive an email and/or text message to be among the first to know about the A4 Study results once they are made public. If you are a participant in the A4 Study, your local study site will also be in contact with you to provide additional details about what the results mean and how they affect you.  

By signing up for an email or text message from the A4 Study, we hope the first time you hear about the study results will be from the A4 Study team. You will receive a confirmation email/text as soon as you sign up. Results are expected in Spring 2023.
