Terminated

Unique provision in the American Recovery and Reinvestment Act prevented approval of second year no-cost-extension in which completion of analyses were planned.

This NA trial investigates Blindness and is currently terminated or withdrawn. Oregon Health and Science University leads this study, which shows 11 recorded versions since 2005 — indicating substantial longitudinal coverage. The change history captured here reflects the iterative nature of clinical trial conduct.
