Types of journal article
Most of the high-impact respiratory journals publish the majority (around 60–80%) of their articles as original reports of research findings. It is usual practice for there to be a collection of editorials in each issue that either comment on an original paper or highlight some other important issue in respiratory practice.
Respiratory journals also publish reviews of topics, either singly or as part of a series. Review articles tend to be commissioned although unsolicited submissions are possible. Most editors will request that any potential topics for review articles are first discussed with the editorial team to avoid overlap and duplication.
One of the most highly regarded types of article is the systematic review. The authors of a systematic review seek to address a research question by conducting a thorough literature search for all published studies addressing that question. Systematic reviews often contain a meta-analysis, which uses statistical techniques to combine and analyse the results of the studies found.
Correspondence on published articles is key to the interaction and engagement of the journal with its readers and should be encouraged. Some journals also accept research letters, which are short reports of pilot research data and observations. Publication of research output as a research letter does however preclude publication of the data in an original paper.
