Clinical Research Manuscript - Typical Format and Key Considerations - Title, Abstract, Introduction, Methods, Results, Discussion

Q: What core structure is commonly used for a clinical research manuscript?

Most journals use the IMRAD structure: Introduction, Methods, Results, and Discussion as the core of the manuscript.

Q: How should the title and abstract be written?

The title should be clear and succinct (typically under 100 characters/15 words) and avoid acronyms or jargon. The abstract should summarize objectives, methods, results, and conclusions as a complete stand-alone description without adding information not covered elsewhere.

Q: What are key requirements for the methods and results sections?

Methods should describe the study design, procedures, and analysis plan in chronological order with enough detail to replicate, including ethical approval. Results should describe findings without background or interpretation, organized in parallel with methods and presented with figures and tables that can stand alone.

Clinical Research Manuscript provides guidance for preparing a journal-ready clinical research article using common section structure. It outlines what each part should accomplish, from crafting a concise title and stand-alone abstract, to writing a funnel-style introduction that identifies knowledge gaps and study aims. It then specifies how to describe ethical approval, design, participants, interventions, data validation, and statistical analysis in methods, followed by parallel, figure- and table-focused results reporting. The discussion should interpret findings, address clinical implications, and present strengths, limitations, and future directions.

Clinical Research Manuscript Typical Format and Key Considerations for Each Section Typical format of a clinical research manuscript The format, including section names, may vary based on the journal. It is essential to review the journal’s guide for authors before formatting your manuscript. Most journals use the IMRAD format (Introduction, Methods, Results, and Discussion) for the core of the manuscript. Title Abstract Introduction The issue/problem (what is known?) Gaps in the literature (what is not known?) Objectives and hypothesis (how does the study address what is not known?) Methods Ethical approval Study design, setting, and timing Study population Intervention/study groups Data collection and validation Statistical analysis plan Results Descriptive statistics of the study population Procedural results and outcomes Results of the statistical analyses Discussion Synopsis of the main findings Interpretation of the findings Interpretation in the context of the literature, including clinical implications Strengths and limitations Summary and future directions References Acknowledgements Conflicts of interest Key considerations for each section Title The purpose is to clearly and succinctly capture the main finding of the research. Aim to use less than 100 characters/15 words. Avoid acronyms, abbreviations, and jargon. Consider using keywords which allows for easier discovery of the manuscript with search. Abstract The purpose is to briefly summarize the study’s objectives, methods, results, and conclusions. Aim to be complete and concise, providing a stand-alone description of the research and the take-home message. Avoid providing any information that is not presented in the remaining sections of the manuscript. Consider writing the abstract last. The word limit is journal specific (refer to the journal’s guide for authors). Introduction The purpose is to provide background information on the topic, highlight the gaps in the literature, and describe the study objectives. Consider following a 3 paragraph format that is structured as a funnel, moving from a broader perspective on the topic and finishing with a narrow focus on the study. What is known about the issue? Why is it important? What is not known about the issue? What is the objective of the study? What does it add to the existing knowledge? Use the present tense, as this section generally presents accepted facts and principles. The typical length is about 350 words. Methods The purpose is to thoroughly describe the study design, procedures, and tools used for data collection and analysis. Use the study protocol as a guide for completing this section. Describe the study in chronological order, providing enough detail so that an investigator in the field could replicate the study. This includes: Statement about ethical approval and informed consent Study design, setting, and timing Study population, including recruitment, inclusion and exclusion criteria, and, if applicable, the randomization process Intervention details, including detailed description of treatment groups Data collection, including origins of samples, and use of validated surveys, instruments, and methodologies (include references) Statistical analysis plan, including power analysis, the statistical analysis of the primary outcome, followed by a description of the analysis of secondary outcomes, and the software used for analysis Use the past tense to describe what was done. The typical length is < 1,000 words, but it may be shorter for simple lab studies and longer for studies involving a new methodology. Results The purpose is to describe the study findings. Avoid including background information or interpreting the results. Organize this section in parallel with the organization of the methods section, with every method described having a corresponding result. Focus on the visual presentation of the findings in figures and tables. They should follow the order in which they are presented in
