Resumo	An original research article is the primary vehicle for reporting new empirical findings in a discipline. Following the IMRaD structure (Introduction, Methods, Results, and Discussion), it represents a researcher's novel data, analysis, and interpretation. The journal article format has been the gold standard for scientific communication since the establishment of the Philosophical Transactions of the Royal Society in 1665.	IMRaD is the standard organizational framework for scientific manuscripts in biomedical and natural sciences research. It separates reporting into four sequential sections—Introduction (why the research was conducted), Methods (how it was done), Results (what was found), and Discussion (what the findings mean)—enabling readers to understand, evaluate, and reproduce the work. Adopted as best practice by the International Committee of Medical Journal Editors (ICMJE) since the 1970s, IMRaD structure is now mandated or strongly recommended by most peer-reviewed journals.
