Systematic Review and Meta-Analysis Feasibility
Before you start, we check for available studies, existing reviews and the potential for meta-analysis, and give you a clear, reasoned opinion.
Study Screening and Selection
We screen your search results against your criteria, by title and abstract or full text, and deliver decisions with exclusion reasons.
Before starting, we agree the screening stage, record count and criteria. The quotation states whether two people screen independently, with disagreements documented. Unavailable texts stay pending and are not excluded automatically.
You receive a decision file with counts for each stage, the selected-study list and full-text exclusion reasons, with one round of corrections.
What you get
- Screening of the agreed stage or stages.
- Selected studies and exclusion reasons.
- Decision file and one correction round.
What is not included
- Database searching or deduplication.
- Full-text retrieval.
- Data extraction or analysis.
What we need from you
- Clear, approved eligibility criteria.
- A deduplicated record file.
- Full texts if full-text screening is needed.

Common questions
When does project work begin?
The estimated delivery period begins after payment is verified and the required non-sensitive materials are received and approved through the agreed communication channel. Each service defines its requirements.
Is publication or manuscript acceptance guaranteed?
No. Publication, acceptance, and assessment decisions belong to the relevant institutions. We do not guarantee publication, grades, or research outcomes.
Can I send research files or patient information here?
This website does not accept research files or patient data. Keep form submissions general and non-sensitive. Any necessary communication process is agreed after review.
How do I track my order?
After you place your order, we email you a link to your private order page. There you can see each stage of the work and its date, what we need from you, and our latest notes, and we email you whenever the stage changes. If you lose the link, open "Track your order" at the bottom of any page and enter your email and order number, and we'll send the link to the email on your order.
