A research article reports the results of original research, assesses its contribution to the body of knowledge in a given area and is published in a peer-reviewed scholarly journal.
Research articles generally consist of the following components:
Before they are published, the editor of the journal to which the manuscript was submitted sends it to experts in the same field for review. These scholars will review the article for, among other things, the appropriateness of its methodology and its relevance to the field.
Evidence-based Articles are used to support and report evidence-based practice (EBP). It "involves an ability to access, summarize, and apply information from the literature to day-to-day clinical problems."
Clinical case study: Clinical case studies present the details of real patient cases from medical or clinical practice. The cases presented are usually those that contribute significantly to the existing knowledge on the field. The study is expected to discuss the signs, symptoms, diagnosis, and treatment of a disease.1,5 These are considered primary literature and usually have a word count similar to that of an original article. Clinical case studies require a lot of practical experience and may not be a suitable publication format for early career researchers.5
Clinical trial: specific to the field of medicine, clinical trials describe the methodology, implementation, and results of controlled studies, usually undertaken with large patient groups.1,5 Clinical trial articles are also long, usually of about the same length as an original research article. Clinical trials also require practical work experience, as well as, high standards of ethics and reliability.5 So this format is more useful for experienced researchers.
