Yes, most review manuscripts include an abstract, with structured formats common for systematic reviews and scoping reviews.
Editors, indexers, and readers scan the abstract first. That brief block sets scope, methods, and takeaways. For review pieces, the abstract also signals the review type, search approach, and the shape of the evidence. While a few outlets publish editorials or narrative overviews without an abstract, mainstream journals expect one. The exact format depends on the review model and the journal’s house style.
Why Review Papers Use Abstracts
Review writing condenses a field. An abstract lets busy readers judge relevance fast. Databases use it for indexing, and journals use it to route the work to the right editors and peer reviewers. For readers who cannot access the full text, the abstract often stands in for the paper. That is why many outlets require headings, word limits, and a crisp description of scope and conclusions.
Types Of Review And Typical Abstract Formats
Different review genres handle abstracts in slightly different ways. The table below maps common types to the usual format and length ranges that journals set in their author guides.
| Review Type | Typical Abstract Format | Usual Word Range |
|---|---|---|
| Systematic Review / Meta-analysis | Structured with set headings (e.g., Question, Data Sources, Study Selection, Results, Conclusions) | 250–350 words |
| Scoping Review | Structured summary of objectives, sources, eligibility, charting, and key themes | 200–300 words |
| Narrative Review | Often structured in 3 parts (e.g., Importance, Observations, Conclusions and Relevance) or a concise unstructured block | 200–300 words |
| Rapid Review | Brief structured abstract noting streamlined methods and limits | 150–250 words |
| Umbrella Review | Structured, highlighting included review types, overlap, and synthesis approach | 250–350 words |
| Evidence Map | Structured overview of scope, categories, and gaps; often pairs with figures | 200–300 words |
Do Review Papers Need An Abstract? Practical Journal Rules
In practice, leading medical titles set explicit abstract rules for review submissions. One well-known example: the JAMA narrative review uses a three-part structured abstract capped at about 300 words with the headings “Importance,” “Observations,” and “Conclusions and Relevance.” Systematic reviews in the same family require a structured abstract of up to about 350 words. These specifics vary across fields, but the pattern is consistent: reviews carry an abstract, and journals say how to format it.
Reporting checklists also point to abstracts as a required element for systematic syntheses. The PRISMA 2020 extension for abstracts lists 12 items to include, such as objectives, eligibility, information sources, risk of bias, and conclusions. Authors use that list to distill a full review into a clear, self-contained summary.
Structured Vs Unstructured: What Editors Expect
Structured abstracts organize the message under headings. That layout helps readers find the answer they want fast. For systematic or scoping work, journals almost always ask for structure because the methods drive credibility. Narrative pieces may allow a single block, but many outlets still prefer headings that mirror the evidence story. If the target journal gives options, choose structure. It improves scan-readability and reduces the odds of desk rejection.
What To Put In A Review Abstract
Your abstract should match the article type. For systematic work, follow the journal’s headings. Keep the wording tight and concrete. Avoid jargon that adds length without meaning. Use numbers where you can. For narrative pieces, write a three-part summary: the topic’s relevance, the main observations, and the practical takeaways for the reader.
Core Elements Most Journals Look For
- Topic and scope: Define the population, intervention/exposure, comparator, and outcomes if applicable.
- Sources and eligibility: Name the databases and the time window you searched, plus high-level criteria.
- Study yield: Mention the count screened and included, or at least the size of the body of evidence.
- Methods signals: Note screening approach, data abstraction, synthesis model, and risk-of-bias tools used.
- Key findings: Give the headline numbers or themes that matter to end users.
- Conclusions: State what the evidence supports and where limits or gaps remain.
Word Limits And Headings You’ll See Often
Many venues cap review abstracts between 250 and 350 words, with headings tailored to the article type. Some ask for a short list of “Key Points” separate from the abstract. Others expect a “Plain Language Summary” for lay readers, common in evidence groups. Plan for these extras early so your text fits without trimming late in the process.
Where To Find The Exact Rules
Always read the destination journal’s guide for authors and any linked reporting guides. Mid-article is a smart place to check and add links to the exact rules you’ll follow. For instance, many health titles reference the PRISMA 2020 abstract checklist for systematic reviews. The JAMA family publishes clear instructions for authors that spell out abstract headings and caps.
Field Differences: STEM, Social Sciences, And Humanities
Expect variation by discipline. In clinical medicine and public health, structured abstracts are the norm for any method-driven review. In engineering and computer science, format is mixed, but many large publishers still set explicit abstract rules. In the social sciences, a structured or semi-structured block is common for systematic and scoping work, while narrative overviews may use a single paragraph. In the humanities, journals often accept unstructured blocks and sometimes shorter word caps, and some outlets use descriptive summaries instead of rigid headings.
Examples Of Policy Language You Might Encounter
The wording shifts by outlet, but it tends to say the same thing: include a structured abstract with set headings and a word limit. The sample entries below give a flavor of the guidance you’ll see in author pages.
| Journal/Body | What It Says About Abstracts | Typical Limit |
|---|---|---|
| JAMA (Narrative Review) | Three-part structured abstract: Importance, Observations, Conclusions and Relevance | ≤300 words |
| JAMA (Systematic Review) | Structured abstract with set headings matching review components | ≤350 words |
| Cochrane | Abstract plus plain language summary; messages consistent across all summaries | Varies by review |
| General Publisher Style | Abstract required; indexing and discoverability depend on it | 200–350 words |
How To Draft A Tight Abstract That Passes Editorial Checks
Start With The Headline Claim
Write the single sentence that captures the main finding or message. Use that as your north star while you draft. If you can’t say the paper’s point in one line, the review may still be scoped too wide.
Map Your Headings To Your Methods
Match each heading to a method choice readers care about: data sources, selection, appraisal, synthesis, and limits. If you did a meta-analysis, mention the model and the scale of the pooled data. If you used a vote-counting summary only, say so plainly.
Quantify Where You Can
Numbers carry weight. Report the number of studies, participants, and any key effect sizes or ranges. For narrative work, quantify the scope in other ways: the number of major themes, or the time span of literature covered.
Trim Redundancy
Remove phrases that repeat the title. Drop filler words and hedges. Replace vague adjectives with concrete details. Convert clauses into compact noun phrases where that helps clarity.
Check Against The Target Guide
Before submission, compare each abstract line to the journal’s rule page and any reporting checklist. Fix mismatches now to avoid a quick reject later.
Common Exceptions And Edge Cases
Conference summaries that recap a theme across sessions may appear without a formal abstract, though many programs still ask for one. Short editorial-style overviews sometimes run without an abstract, especially in newsy sections. Preprints generally accept abstracts for reviews, and indexing services favor them. If a venue allows posting a “summary box” or “key points,” treat that as a complement, not a replacement.
Plain Language Summaries And Lay Abstracts
Health evidence groups often publish a lay summary alongside the academic abstract. Cochrane is the best-known case. A plain language summary translates the same findings into everyday wording for patients, policymakers, and general readers. Many journals in clinical fields now invite or require this extra. Plan for it during scoping so the messages align and lengths stay within limits. See the Cochrane guidance on aligning the abstract with the lay summary in the author handbook chapter on reporting.

Frequently Asked Nuances
Is One Sentence Enough?
No. Journals expect a paragraph-length abstract. A one-liner belongs in the title or key points section, not the abstract field.
Do You Cite Sources Inside The Abstract?
Rarely. Most journals ask authors to avoid references in the abstract. If a citation is unavoidable, spell out the name rather than dropping a bracketed number string.
Can You Include Tables Or Figures Inside The Abstract?
Almost never. Keep tables and figures in the main text or the supplement. The abstract should stand on its own in plain text.
Bottom Line For Authors
For reputable outlets, a review needs an abstract. Use structure when the journal allows it, and follow the headings it asks for. Anchor the text in methods, scale, and clear takeaways. Link your work to the exact rules the journal cites, and check PRISMA’s abstract extension when you are reporting a systematic synthesis. That approach serves readers, satisfies indexers, and speeds editorial decisions.
