The OAI Online website that has been hosted by the OAI Coordinating Center at the University of California San Francisco the past 12 years has been taken down.

All OAI data will continue to be available by accessing a new website that is hosted by the National Institutes of Health. The URL for this new website is:

OAI investigators at the OAI Coordinating Center, University of California San Francisco ( remain open to collaboration with other investigators on projects using OAI data and images; we look forward to hearing from you!

Once again, thank you for your continued interest in and support of the Osteoarthritis Initiative!
