PubMed Health specializes in reviews of clinical
effective research – which finds answers to ‘What
Works’ in medicine and health care. It is based on
systematic reviews of clinical trials.
PubMed Health is a service provided by the National
Center for Biotechnology Information (NCBI) at the
U.S. National Library of Medicine (NLM).
From the Contents drop down menu, you can
