Principles and Practice of Clinical Research


Globalization has contributed significantly to the dissemination of information in different areas of knowledge. Scientific papers are therefore the way to contribute to this global debate and advance in science. 

PPCR will therefore contribute to disseminate the latest research and updates on clinical research.

PPCR aims to providing a medium for the publication of scientific articles of high quality, thus promoting the work and training of clinical researchers globally. 

The journal is initially expected to be quarterly and will be open for new submissions from April 2015.
