Literature Review Template: Outline, Matrices & Examples

This literature review template gives PhD writers a downloadable chapter outline, a source matrix with one paper per row, and a synthesis matrix with one claim per row. Start with your research question, fill each evidence cell from a paper you have checked, then draft around comparisons rather than article-by-article summaries.

Use this structure for your own analysis, then consult the step-by-step literature review guide for search, selection and synthesis methods.

TL;DR

• Copy the literature review template into a chapter plan and make each section advance a claim.

• Use a literature review matrix to record each paper’s evidence and source location.

• Use a synthesis matrix to compare papers by claim, method and outcome.

• AnswerThis can help identify candidate papers; verify each consequential statement in the original.

Literature review template

A basic comparison matrix uses Question, Method, Sample, Finding, Limitation and Your note. Keep a source identifier and exact evidence location alongside those fields; the additional source-level and claim-level matrices below show how to separate extracted facts from interpretation.

This is a writing scaffold, not a prescribed thesis structure. Check your programme’s requirements before fixing the headings.

A spreadsheet does not make a search systematic. A systematic review needs a planned, documented method for finding, selecting and appraising studies. Use the separate systematic literature review guide for that process.

Use the outline as a drafting scaffold

Start with the claim your section needs to establish, then use the source matrix to retrieve the supporting details and the synthesis matrix to test how papers agree, qualify, or limit that claim.

Literature review matrix: one paper per row

A literature review matrix is a source-level record. It makes your notes comparable and your claims traceable. Copy these headers into a spreadsheet:

[Verify paper and DOI]

• Source type and question: [Experiment, review, theory; aim]

• Design, population and setting: [Design, participants, context]

• Comparison and outcome: [Conditions, measure, timing]

• Relevant finding: [Report only what the source states]

• Author-stated limitation: [Quote or paraphrase with location]

• Evidence location and check status: [Page, table, figure or abstract; checked or not yet checked]

Copy the headers into a spreadsheet. Keep a separate my appraisal column so your interpretation is never mistaken for an author-reported result; add a theme column only when it helps group the papers.

Use evidence location for a page, table, figure or section you can return to. Keep the author’s finding separate from your appraisal. Write not reported only after checking the relevant text, not yet checked when you have not inspected it, and not applicable when the field does not fit the source. A blank cell cannot distinguish these states.

Worked literature review matrix example

Suppose the review asks: How does practice testing compare with restudying for retention? These are identifiable publications. The entries below are provisional extractions from publication records and abstracts, not full-text appraisals. In your spreadsheet, record the evidence location as “abstract; full text not yet checked” until you have inspected the original results and methods.

Roediger & Karpicke (2006), Test-Enhanced Learning: Taking Memory Tests Improves Long-Term Retention

• Type and comparison: Experiments comparing free-recall testing with restudying using prose passages.

• Relevant finding: Restudying performed better after 5 minutes, while prior testing produced better retention after 2 days and 1 week.

• Evidence location and check status: Full text checked, Experiment 1, Final Test results.

Dunlosky et al. (2013), Improving Students’ Learning With Effective Learning Techniques

• Type and comparison: Review evaluating evidence for 10 learning techniques.

• Relevant finding: Practice testing and distributed practice received high-utility assessments.

• Evidence location and check status: Full text checked, overall assessment sections for practice testing and distributed practice.

Rowland (2014), The Effect of Testing Versus Restudy on Retention

• Type and comparison: Meta-analysis of testing versus equivalent-duration restudy.

• Relevant finding: Recall-based initial tests produced larger testing benefits than recognition tests, and benefits were larger at retention intervals of at least 1 day.

• Evidence location and check status: Full text checked, moderator analyses.

The sources play different roles. Roediger and Karpicke provide a specific experiment. Dunlosky and colleagues assess learning techniques across a broader literature; Rowland examines results across testing studies. A review that discusses an experiment is not an independent replication of it.

For your project, add only fields you will compare. A clinical review might need intervention duration and outcome definition; a qualitative review might need recruitment and analytical approach. A wider matrix is not necessarily a more useful one.

Synthesis matrix: one claim per row

The synthesis matrix is a separate planning tool. Each row asks what several papers, considered together, allow you to say about one theme or claim.

A paper can support one claim and qualify another. Assign findings to claims rather than labelling whole papers “supporting” or “conflicting.”

Worked synthesis matrix example

The final-test interval changes the testing-versus-restudying comparison

• Evidence to compare: Roediger & Karpicke compare immediate and delayed final tests; Dunlosky et al. assess practice testing across a broader literature

• Qualification to investigate: An evidence review does not replicate this particular experiment; do not collapse immediate recall and delayed retention

• Defensible conclusion: Lead a section with the interval-dependent result, then assess how far broader evidence supports its application.

Initial-test format may qualify a comparison

• Evidence to compare: Rowland reports larger testing benefits after initial recall than recognition tests; Roediger & Karpicke use free recall

• Qualification to investigate: Test format is not the only difference across studies, and a meta-analytic pattern cannot be assigned to one experiment

• Defensible conclusion: Extract format and final-test timing separately before explaining any cross-study difference.

The first row could become a paragraph:

The timing of the final test changes how testing and restudying should be compared. In Roediger and Karpicke’s experiments, repeated studying improved recall after five minutes, while prior testing improved retention on delayed tests. Dunlosky and colleagues’ broader evaluation places practice testing among useful learning techniques, but does not erase that distinction in the experiment. A review of retention should therefore specify when the outcome was measured before stating which approach performed better.

The paragraph uses the experiment for a precise result and the broader review for context. It does not make both sources perform the same evidential job. The literature review matrix records what each paper says; the synthesis matrix tests what you can say across papers.

Turn matrix rows into a structured draft

Use the source matrix to retrieve verified details from individual papers, then use the synthesis matrix to group those details around one claim, qualification, or unresolved difference. The outline turns that structured comparison into a chapter draft.

The worked matrix above uses publication abstracts, so its entries are provisional and abstract-based, not a full-text appraisal. If a paper has only an abstract available, label the source location accordingly. An unfilled field is not proof that the paper omitted the information.

From matrices to a structured draft

Use AnswerThis to connect paper discovery, organization, extraction, and synthesis. Find candidate papers and save or upload relevant sources to your library. Use custom columns or paper extraction to record comparable fields such as study design, population, outcomes, findings, and limitations, while keeping evidence quotations and source locations available for verification. After reviewing those entries against the original papers, use the structured evidence to build your claim-led synthesis matrix. The AnswerThis literature review generator can separately help you begin with an abstract-based outline, cited opening paragraph, linked scholarly sources, and search scope. Keep unverified details marked “not yet checked” and make the final inclusion and interpretation decisions yourself.

Mistakes that weaken a PhD literature review

• One paragraph per paper: Group papers under a claim and compare them; keep the paper-led details in the source matrix.

• An untraceable “key finding” cell: Record the outcome, comparison and source location so you can verify the claim later.

• Different measures treated as the same result: Record what each study measured and when.

• Reviews counted as new experiments: Identify source type to avoid double-counting the same underlying work.

• An empty cell treated as a gap: Distinguish “not reported” from “not yet checked,” then search specifically for the supposedly missing work.

• A polished generated draft accepted as evidence: Follow its references back to the papers and check consequential claims.

Use these editable files to capture source-level evidence, compare claims across studies, and move verified material into a structured draft. For the full writing workflow, read How to Write a Literature Review. For finished models, see Literature Review Examples.

What these templates help you do

Use these templates to turn individual papers into traceable source rows, compare evidence across claims, and build a chapter draft from verified details rather than article-by-article notes.

For a thesis chapter, the reader needs to see why your question follows from existing work. A matrix makes the source trail visible, while the outline makes the reasoning legible.

FAQs

Which fields make this literature review template traceable?

Record the citation, design, population, comparison, outcome, finding and limitation, plus the exact supporting page, table or section. Keep your appraisal separate from author-reported information.

Why does the source matrix use one paper per row, but the synthesis matrix one claim?

The source matrix records what each paper says. The synthesis matrix compares supporting and qualifying findings across papers to test a claim and plan a section.

How do I turn the practice-testing matrix example into an analytical paragraph?

Lead with how final-test timing changes the comparison, then contrast immediate recall with delayed retention. Use broader reviews for context, not as independent replications of the experiment.

When should a matrix cell say “not reported” rather than “not yet checked”?

Use “not reported” only after checking the relevant source text. Use “not yet checked” for unverified details and “not applicable” when a field does not fit the source.

How can AnswerThis support my source table and synthesis matrix?

AnswerThis literature review generator retrieves linked scholarly sources and creates an abstract-based literature review outline plus one cited opening paragraph. Use those sources as candidates for your review, then verify the full papers. In the broader AnswerThis workspace, you can save or upload papers, organize them in a library, use custom columns or structured extraction for fields such as design, population, outcomes, findings, and limitations, and compare evidence across papers. After checking the extracted information against the originals, use those records to build your claim-led synthesis matrix.

One last thing

A full matrix is not the goal. The test is whether a reader can trace each important chapter claim through your synthesis back to the original evidence, including papers that limit it.
