Is it theoretically possible for the 95% confidence interval about the hazard ratio to include 0, such that the lower bound is a negative number? I've encountered into this with a program I've written (too long to post here, and I don't want to bother anyone), but I'm certain I've done something incorrectly. Might someone have a moment to clarify this question?


Best wishes,
