A critical review of a journal article is an evaluation of an article's strengths, weaknesses and validity. It is used to inform readers of an article's value through explanation, interpretation and analysis. The reviewer must present information that will allow the reader to make a value judgment about the article.
Peer review is a central part of this medical journal publication process, held as the best available means to help check the quality, relevance and importance of papers being submitted by medical researchers. This in turn helps to ensure that medical treatments are safe and effective for patients.
