Keeping Up? Do nothing and get out of date Depend solely on courses/conferences Choose the main professional journal(s) and
read them cover to cover every month

Evidence Pyramid
Important medical questions are typically studied
more than once, often by different research teams in
different locations. A meta-analysis combines resultsfrom different studies, hopefully averaging out anydifferences caused by random change or localvariation and getting at something close to the realtruth. In general a meta-analysis, if you can find one,
will be a better guide to practice than an individualarticle.
