Unclear Review Question
Broad or shifting scope can make the search and eligibility criteria inconsistent. Focus: clarify the review question and core concepts.

Common Systematic Review Issues We Help Address
A systematic review can become difficult to reproduce when the research question, search logic, screening rules, extraction fields, appraisal approach, or reporting trail are not clearly defined.
Search Strategy Gaps
Missing synonyms, concept blocks, or database-specific syntax can weaken search reproducibility. Focus: structure transparent search logic.
Screening Inconsistency
Eligibility rules that are open to interpretation can produce inconsistent study decisions. Focus: define decision-ready criteria.
Illustrative review framework
How should the review question, eligibility criteria, and outcome fields connect?
The review framework should create a consistent path from the research question to the search concepts, screening rules, extraction form, appraisal method, and synthesis plan.
| Element | Decision rule | Status |
|---|---|---|
| Population | Defined characteristics and setting | Defined |
| Intervention / exposure | Prespecified concept and comparator where relevant | Defined |
| Outcomes | Primary and secondary outcome fields | Check |
| Study design | Eligible designs stated before screening | Defined |
Extraction Design Problems
Overly broad or inconsistent fields can make evidence synthesis harder. Focus: use a structured extraction framework.
Critical-Appraisal Mismatch
The appraisal approach needs to fit the included study designs. Focus: align appraisal planning to the evidence base.
Reporting Gaps
Missing search records, exclusion reasons, or decision logs reduce transparency. Focus: maintain a traceable review record.

What the Systematic Review Service Covers
The service can be scoped around one stage or a broader review workflow, depending on the materials you already have and the methodological support required.
Review Question & Protocol Structure
Define the review objective, concepts, eligibility criteria, outcomes, and decision rules so later stages connect back to the same scope.
Search Strategy Development
Organise search concepts, synonyms, Boolean logic, database syntax, and search documentation for a reproducible retrieval process.
Screening Workflow
Translate eligibility criteria into consistent title/abstract and full-text decisions, with reasons recorded where required.
Data Extraction & Critical Appraisal
Structure study-characteristic and outcome fields, then align critical-appraisal planning with the types of studies included.
Evidence Synthesis & Reporting
Organise the evidence narrative, tables, review flow, limitations, and reporting structure so the methods and findings remain traceable.

Demonstration — A Systematic Review Workflow in Practice
The example below shows how different review decisions connect. It is an illustrative workflow, not a claim about any specific client project.
From a broad topic to a traceable review process
A broad topic becomes a review-ready question by defining the population or context, intervention / exposure or phenomenon, outcomes or concepts of interest, and eligible study designs. These same elements then guide the search strategy, screening criteria, extraction form, appraisal approach, and synthesis plan.
Question frameworkSearch conceptExtraction fieldEligibility rule

Before → Review Support → Structured Final Workflow
Systematic review support is intended to make the review process clearer and more traceable rather than simply polishing the final manuscript language.
Initial Review Plan
Search several databases for papers about the topic.
Include relevant studies and extract useful information.
Summarise the results and discuss limitations.
Typical risk: broad instructions leave room for changing definitions and inconsistent decisions.
Structured Review Support
Define the review question, concepts, eligibility rules, and outcomes before screening.
Translate concepts into a documented search strategy and database-specific syntax.
Use consistent screening, extraction, appraisal, and evidence-summary structures.
The workflow is organised so each decision can be traced back to the review objective and protocol.
Review-Ready Structure
A defined methodology connects the question, search, eligibility criteria, extraction, appraisal, synthesis, and reporting.
Decision logs and review tables support transparent reporting.
The manuscript can then be written around a documented evidence-synthesis process.
Final deliverables depend on the agreed project scope.

Systematic Review Support vs. Advanced Editing
These services solve different problems. Systematic review support focuses on evidence-synthesis methodology and workflow; editing focuses on language, clarity, consistency, and presentation of an already developed document.
| Aspect | Systematic Review Service | Advanced Editing |
|---|---|---|
| Primary focus | Review methodology, search, screening, extraction, appraisal, synthesis, and reporting structure | Language accuracy, sentence clarity, academic tone, consistency, and presentation |
| Research question | Methodological focus — can structure the question and eligibility framework | Limited — edits wording rather than redesigning the evidence-synthesis method |
| Database search | Methodological focus — search concepts, synonyms, Boolean logic, and documentation | Not the primary scope |
| Screening & extraction | Methodological focus — workflow, criteria, fields, and traceability | Not the primary scope |
| Manuscript language | Can be addressed where agreed as part of reporting support | Core focus — grammar, clarity, tone, consistency, and sentence-level refinement |
| Best used when | The review method or evidence-synthesis workflow needs structured support | The research content is developed and needs language and presentation improvement before submission |

Custom Systematic Review Quote
No fixed price is stated for this service because systematic review projects can differ substantially in scope. A tailored quote can be prepared after the review stage, expected inputs, and required deliverables are understood.
Scope-Based Quote
Share the current status of your review and the stages for which you need support. The quote can then reflect the actual methodological workload rather than an unsupported fixed package.
Search Scope
Number and type of information sources, concepts, and search complexity.
Screening Volume
Record volume, screening stages, and full-text eligibility workload.
Extraction Depth
Number of fields, outcomes, time points, and study characteristics.
Appraisal Method
Study designs included and the appraisal structure required.
Synthesis Depth
Evidence tables, narrative synthesis, and reporting complexity.
Deadline
Requested completion date and feasibility after scope review.
12
Confidentiality & File Handling
Systematic review materials can include unpublished protocols, screening records, extraction tables, manuscripts, and research notes. These materials should be handled as confidential service information through the designated workflow.
Confidential Research Materials
Client information, unpublished research content, and working review files are treated as confidential within the service process.
Controlled Working Files
Use the designated submission and delivery process for protocols, database exports, screening logs, extraction files, and manuscripts.
Need-to-Know Handling
Project materials should be shared only with the people needed to complete the agreed service scope.
Traceable Review Records
Where the scope includes screening, extraction, or appraisal, working records should remain clear enough for author review and methodological traceability.
13
Turnaround Is Confirmed After Scope Review
No fixed turnaround is published for this service. Delivery timing is confirmed after the review stage, evidence volume, methodological complexity, expected outputs, and requested deadline are assessed.
Current Review Stage
A protocol-only project has a different workload from screening, extraction, synthesis, or full reporting support.
Evidence Volume
Search results, full-text records, included studies, outcomes, and extraction fields influence the review workload.
Deliverable Depth
Search documentation, logs, appraisal records, evidence tables, synthesis notes, and manuscript support are scoped separately.
Share your target date in the enquiry. Feasibility can be assessed once the current project status and required outputs are clear.

Frequently Asked Questions
These answers explain how a scope-based Systematic Review Service can be organised. The exact methodology, deliverables, price, and timing are confirmed for the individual project.
What is included in a Systematic Review Service?
The exact scope is agreed for each project. Support can cover review-question framing, eligibility criteria, search strategy, screening workflow, data extraction structure, critical appraisal planning, synthesis support, and transparent reporting.
Can you work from an existing protocol?
Yes. If you already have a protocol, search strategy, screening criteria, extraction framework, or manuscript draft, those materials can be reviewed as the starting point for the agreed scope.
Can the service focus only on the literature search?
Yes, the project can be scoped around search-strategy development and documentation if that is the stage where you need support. The review question and eligibility criteria should be sufficiently clear to guide the search.
Can the service support screening and eligibility decisions?
Screening support can be scoped around prespecified eligibility criteria, title/abstract decisions, full-text review, and exclusion-reason documentation. The exact workflow should be agreed before screening begins.
What information is needed for data extraction?
The extraction form should capture the study characteristics and outcomes needed to answer the review question and support the planned synthesis. The fields depend on the evidence designs and review objectives.
Do you support risk-of-bias or critical appraisal?
Critical-appraisal support can be included where agreed. The appraisal approach needs to be suitable for the types of studies included in the review rather than applied as a one-size-fits-all checklist.
Can you help with the synthesis and review manuscript?
Evidence-synthesis and reporting support can be included in scope, such as organising evidence tables, narrative synthesis, limitations, methods/results structure, and review-flow reporting. The exact depth depends on the evidence base and agreed deliverables.
Do you provide a fixed price for systematic review projects?
No fixed price is stated on this page. A quote is prepared after the project scope is understood, including the databases, search complexity, screening volume, extraction requirements, appraisal method, synthesis depth, and reporting needs.
How is turnaround determined?
Turnaround is confirmed after scope review because the effort depends on the research question, database coverage, record volume, full-text screening needs, extraction fields, appraisal approach, synthesis requirements, and requested deadline.
Can I submit database exports or screening files?
Yes. Existing search exports, screening spreadsheets, extraction tables, protocols, notes, and manuscript files can be useful for understanding the current stage and defining the scope.
Will my unpublished review materials remain confidential?
Unpublished protocols, research notes, search files, screening records, extraction tables, manuscripts, and client information should be handled as confidential service information through the designated submission and delivery process.
How do I know whether I need systematic review support or editing?
Choose systematic review support when the evidence-synthesis method or workflow needs help. Choose editing when the research and review process are already developed and the main need is grammar, clarity, academic tone, consistency, or presentation. A project can require both at different stages.
What to include in your enquiry
