IMRAD
IMRAD is the standard organizational structure for scientific research articles, standing for Introduction, Methods, Results, and Discussion.
1Detailed Explanation
IMRAD format was established in the late 1970s and is now the globally accepted standard for organizing original research articles in medicine, biology, and most scientific disciplines. The structure ensures that research papers contain all essential elements in a logical flow: background and rationale (Introduction), how the research was conducted (Methods), what was found (Results), and what the findings mean (Discussion). Most high-impact medical journals including NEJM, JAMA, Lancet, and BMJ require IMRAD format for original research articles. Some journals have adapted variations, such as adding 'Conclusion' as a separate section or combining Results and Discussion.
