Hi Paul, EBH-ers,
You probably already know about this but just in case---doesn't deal with
ignoring or contradicting, but points out, for example, that about 0.3% of
(American Heart Association/American College of Cardiology) guidelines
related to management of valvular heart disease have an evidence base, about
11% for atrial fibrillation.
