abstract-and-title

Titles, Abstracts and Summary Text

Most readers, editors and reviewers decide from the title and abstract alone. They are also what search engines and indexing services see. Write them last, from the finished results, and revise them more than any other part of the paper.

Inputs to collect first

• The single main finding, with its key number (effect size, accuracy, p-value/CI, sample size).
• The target venue's limits: abstract word count, structured vs. unstructured, title length, keyword count, highlights/significance requirements. Look these up in the venue's current author guidelines (the venue-templates skill and journal-format skills help). Never assume.
• Who reads it: specialists (field venue) or broad scientists (Nature, Science, PNAS).

Abstract: the five-move structure

Unstructured abstracts still follow these moves. Structured ones label them.

Move	Share	Content
Context	1 sentence	The broader problem, in terms the venue's readers care about
Gap	1 sentence	What is unknown, unsolved or wrong. Make the gap concrete
Approach	1-2 sentences	What you did: design, data, method, with the essential scale (n, datasets)
Results	2-3 sentences	The main findings with numbers. Lead with the most important
Implication	1 sentence	What changes because of this, bounded by what the evidence supports

Structured formats: IMRaD (Background/Methods/Results/Conclusions) for most clinical journals. CONSORT-for-abstracts for RCTs. PRISMA 2020 for Abstracts for systematic reviews. Some journals (e.g. BMJ) use their own headings, so match the journal exactly.

Rules:

• Numbers beat adjectives: "reduced error by 23% (95% CI 18-28%)" not "substantially reduced error".
• No citations, undefined abbreviations, or claims not in the paper. Define an abbreviation only if used ≥2 times.
• Past tense for what you did and found; present tense for established facts and implications.
• Keep it self-contained: a reader should understand it without the paper.
• Hit the limit without padding. If over, cut context before results.

Titles

Generate 5-10 candidates across types, then pick against the criteria:

• Declarative (states the finding): "Metformin reduces hepatic glucose output via complex IV inhibition". Common in biology/medicine and broad journals.
• Descriptive (states the topic/method): "A graph neural network for retrosynthesis planning". Common in CS/engineering.
• Question: use sparingly, only when the answer is genuinely surprising.

Criteria: accurate (no overclaiming), specific (organism, method, population), contains the 2-3 terms people search for, within the venue's length limit, no abbreviations except universal ones (DNA, MRI), no puns that hide the content. Check that no existing paper already has a near-identical title.

Keywords

Choose terms not already in the title to widen discoverability: synonyms, the broader field, method names, organism/population. Prefer controlled vocabulary where the venue uses it (MeSH for biomedicine, ACM CCS concepts, IEEE Taxonomy, JEL codes, PACS/PhySH).

Venue-specific extras

Element	Typical form (verify per venue)
Highlights (Cell Press, Elsevier)	3-5 bullets, each up to ~85 characters including spaces, results-focused
eTOC blurb / In Brief (Cell Press)	Short third-person paragraph for non-specialists
Significance statement (PNAS)	Plain-language paragraph on why the work matters to a broad audience
Author summary (PLOS)	Non-technical summary for a general reader
Lay / plain-language summary	Health and life-science journals, funders: no jargon, ~reading age 12-14
Graphical abstract	One image read left-to-right or top-to-bottom: problem → approach → key result
Teaser / tweet-length	One sentence with the key number, for press and social media

Revision checklist

1. Does the first sentence establish why this matters to this venue's readers?
2. Is the gap stated explicitly, not implied?
3. Does every result sentence contain a number or concrete outcome?
4. Is every claim supported in the main text, at the same strength?
5. Word count within the limit (count it, don't estimate)?
6. Would a researcher from an adjacent field understand it?
7. Do title, abstract, highlights and conclusions tell the same story with the same numbers?
