Manuscript Structure

Introduction Section

The Introduction establishes the context and rationale for the study, moving from broad knowledge to the specific research gap and objectives.

1Detailed Explanation

The Introduction follows a 'funnel' structure in IMRAD format: 1) General context and importance of the topic (1-2 paragraphs), 2) What is already known about the topic (literature review), 3) What is unknown or what gap exists (rationale), 4) Study objectives or hypotheses. Length varies by journal (typically 400-600 words). Avoid citing too many references (focus on most relevant), and avoid including results or conclusions. The Introduction should end with a clear statement of objectives. Common mistakes include: being too broad or too detailed, not clearly identifying the gap, burying the research question, and including a mini-results section.

2Examples

  • A.A well-structured introduction: global burden of disease → current treatment landscape → limitations of existing evidence → specific gap → study objective
  • B.Poor introduction: starts with the study aim without establishing context or identifying gaps

3Why It Matters in Research

The Introduction sets the stage for your study. A compelling, well-structured introduction engages reviewers and contextualizes the study's importance.
