Practical abstract-formatting guide
- Paste and clean. Load your own text or an example, then review optional PDF, punctuation, and LaTeX cleanup in the preview.
- Match the venue. Choose unstructured, IMRaD, IMRaC, or the exact heading set required by your journal or conference.
- Check and copy. Resolve structural checks, review heuristic suggestions, confirm the venue’s count, and copy the required output.
Structured versus unstructured: a structured abstract labels its parts so readers can scan the study design and findings. An unstructured abstract presents the same summary as one paragraph. Remove headings when the venue asks for a single paragraph; never retain headings merely because the source manuscript used them. The ICMJE manuscript recommendations note that structured formats differ by journal and authors should follow the selected journal’s format.
What each section should do
| Section | Purpose and suggested content | Example phrasing |
|---|---|---|
| Background | Brief context and the unresolved problem; roughly 10–20% of the abstract. | “Urban heat exposure is rising, but block-level shade effects remain uncertain.” |
| Objective | The study question, aim, or hypothesis; roughly 5–10%. | “We tested whether added shade reduced afternoon surface temperature.” |
| Methods | Design, setting, sample, intervention or exposure, outcomes, and analysis; roughly 25–35%. | “We compared 24 matched street segments over six summer weeks.” |
| Results | The main specific findings, preferably with quantities and uncertainty where appropriate; roughly 30–40%. | “Shaded segments were 3.1°C cooler (95% CI 2.4–3.8).” |
| Conclusion | The supported interpretation, significance, and important limitation; roughly 15–25%. | “Targeted shade may reduce pedestrian heat exposure in dense blocks.” |
These allocations are planning suggestions, not rules. ICMJE asks research abstracts to cover context, purpose, basic procedures, main findings, and conclusions; it also advises giving specific effect sizes where possible and avoiding overinterpretation. For randomized trials, consult the current CONSORT guidance. Your venue’s author instructions always take precedence.
Formatting text copied from a PDF
Keep genuine paragraph breaks, join visual line wraps, and repair only hyphens introduced at a line end. The repair option removes a line-end hyphen when a letter is followed by a lowercase continuation, so review real compounds carefully. If a PDF has columns, tables, or reading-order errors, use the original source rather than assuming automatic cleanup is correct.
