Correction: Which Beta-Blocker is Best for Patients with Heart Failure?

In the summary “Which Beta-Blocker is Best for Patients with Heart Failure?” published online on December 17, 2008, the second sentence in the Comment, which originally read:

The findings suggest that metoprolol tartrate is not as effective as is atenolol or carvedilol.

should read as follows (added text indicated in bold):

As noted by the author of an invited commentary, other trial findings have suggested that metoprolol tartrate is not as effective as is atenolol or carvedilol.

Many thanks to Neil Hall of Cary, North Carolina, for pointing out this discrepancy.
