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.
Meta-Analysis
We run the meta-analysis on your extracted, checked study data and deliver results, plots and analysis files.
Completed 17 times
We review your protocol and dataset and confirm that pooling is appropriate before starting. We then choose suitable effect measures and models, assess heterogeneity and run the agreed subgroup and sensitivity analyses.
Findings are reported as they are, whether or not they are statistically significant. If pooling is not appropriate, we explain why and stop before analysis. You receive a results report, forest plots and analysis files, with one round of corrections.
What you get
- A check that pooling is appropriate.
- Analyses and comparisons set in the quotation.
- Heterogeneity and publication-bias checks where possible.
- Results report, plots and analysis files.
What is not included
- Searching, screening or data extraction.
- GRADE certainty assessment unless added.
- Network meta-analysis or individual participant data.
What we need from you
- An approved protocol and analysis plan.
- Extracted and checked study data.
- Risk-of-bias results if the analysis needs them.

Common questions
Should I choose a service or request a quote?
A service with a defined scope and fixed price can be added to your cart. If the scope is variable or unclear, request a quote and review it before accepting it.
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.
