Let's say the 180th event takes place in July 2008, and enrollment is completed in Sept 2007. There will be a lot of survivors in both arms who enrolled 10-15 months prior to 7/08. These patients still need to be counted in the overall intent to treat survival analysis...so there won't be much of a difference in the survival curves for these recent enrollees...thus hurting the overall p value.
