Key points at a glance
- Your research question determines the appropriate review approach.
- A systematic review requires explicit, justified methods.
- PRISMA supports reporting; it does not replace a research method.
Clarify what the review should establish
A literature review evaluates and connects existing research. Before choosing a label, define your intended outcome. Do you want to interpret theoretical positions, map a research field or answer a focused question using eligible studies? These aims require different approaches.
Scope matters as well. A bachelor thesis can be methodologically careful without covering every publication in a large field. The important connection is between the question, search, selection and synthesis. Explain the boundaries of that connection openly.
Distinguish narrative and systematic approaches
A narrative review may bring together concepts, developments or competing explanations. Selection is often more flexible, but the choice of sources and the argument still need justification. A series of unrelated paper summaries is not yet a synthesis.
A systematic review uses an explicit question and transparent procedures for searching, selecting, appraising and synthesising evidence. Cornell provides a decision aid for these distinctions. Check whether you can carry out the required work within your schedule, including obtaining and examining full texts.
Place scoping reviews and meta-analysis correctly
A scoping review typically maps the extent and characteristics of a research area. It is not simply a substitute for a systematic review that seems too demanding. Mapping a field also requires justified methods and explicit eligibility criteria.
Meta-analysis statistically combines suitable results. Not every systematic review includes one. Differences in design, measurement or context can make another form of synthesis more appropriate than pooling estimates.
Original example: “Which concepts of digital belonging are used?” calls for identifying and interpreting concepts. “What effect does a defined intervention have on a specified outcome?” requires a different selection and appraisal process. Let the question determine the label.
Agree on a feasible method
Outline databases, eligibility rules, screening, appraisal and planned synthesis before starting. Discuss the required steps and acceptable limitations with your supervisor. If you screen studies alone, state that clearly rather than describing an independent second review that did not happen.
PRISMA 2020 provides reporting guidance for systematic reviews. Completing a flow diagram does not establish that the search or appraisal was adequate. Use relevant reporting elements to make the work transparent, and justify the research methods separately.
Final submission context
Formal details can feel like a separate writing task, but they matter just as much for a printed submission. Anything missing, misplaced or inconsistently formatted in the document will also appear in the bound copy.
Use this guide together with your cover page, table of contents, page numbers, source notes and appendices. Prepare the final PDF for printing and binding only after the complete file has been checked.
Practical check before PDF export
- Do headings, chapter structure and page numbers match?
- Are sources, figures and tables included completely?
- Are required elements such as declarations, appendices or the cover page included where required?
- Did you open and check the final PDF after exporting it?
Checklist
- Define the intended contribution.
- Match the review label to the actual method.
- Check search and full-text access feasibility.
- Plan selection and synthesis in advance.
- Disclose methodological limitations.
Common mistakes
- Calling every literature-based thesis a systematic review.
- Treating PRISMA as a complete research method.
- Forcing a meta-analysis when results are not sufficiently comparable.

Frequently asked questions
Is a narrative review less academic?
Not automatically. Quality depends on whether the approach fits the question and the argument is transparent. A narrative review still needs critical interpretation and a defensible selection of sources.
Can I conduct a systematic review alone?
This may be possible for a student project, but it introduces limitations. Agree on expectations and explain which steps you completed alone and how you reduced avoidable errors.
Do I need statistical analysis?
No. The synthesis depends on your question and evidence. A justified qualitative or structured narrative synthesis can be appropriate within a systematic review; it does not automatically change the overall design into a narrative review.
