From Cyrus Mehta, Cytel President, Co-Founder:

“East 5 builds on East’s reputation for versatility and accuracy. Many of the new features in East 5 came from ideas provided by our users, for example better ways to share trial concepts amongst non-statisticians like "Split Screen" and displaying of multiple graphis to compare results. Helping our customers confidently determine the best design and clearly communicate the design's concepts is what East 5 is all about.”
