Review article in the context of Primary source

An academic journal (or scholarly journal) is a periodical publication in which scholarship relating to a particular academic discipline is published. They serve as permanent and transparent forums for the dissemination, scrutiny, and discussion of research. Unlike professional magazines or trade magazines, the articles are mostly written by researchers rather than staff writers employed by the journal. They nearly universally require peer review for research articles or other scrutiny from contemporaries competent and established in their respective fields. Academic journals trace their origins back to the 17th century, with the Philosophical Transactions of the Royal Society being established in 1665 as the first scientific journal.

As of 2012, it is estimated that over 28,100 active academic journals are in publication, with scopes ranging from the general sciences, as seen in journals like Science and Nature, to highly specialized fields. These journals publish a variety of articles including original research, review articles, and perspectives. The advent of electronic publishing has made academic journals more accessible.

Scientific consensus is the majority judgment and position by active, qualified experts in a specific scientific discipline to establish a conclusion or fact. Scientific consensus results from the self-correcting scientific process of peer review, replication of the event through the scientific method, scholarly debate, meta-analysis, and publication of high-quality review articles, monographs, or guidelines in reputable books and journals to establish facts and durable knowledge about the topic.

Reaching consensus requires significant scientific agreement among qualified experts, a process based on scientific substantiation of a claim that meets the burden of proof by proposing a possible cause-and-effect mechanism supported by the totality of evidence, leading to agreement among experts. In many countries, scientific consensus established on significant scientific agreement is the basis for regulatory approval of drugs to specify a health claim for the properties of the approved therapeutic agent.

The Lancet is a weekly peer-reviewed general medical journal, founded in England in 1823. It is one of the world's highest-impact academic journals and also one of the oldest medical journals still in publication.

The journal publishes original research articles, review articles (divided into seminars and reviews), editorials, book reviews, correspondence, as well as news features and case reports. The Lancet has been owned by Elsevier since 1991, and its editor-in-chief since 1995 has been Richard Horton. The journal has editorial offices in London, New York City, and Beijing.
