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 Data Extraction
We extract data from the full texts of your selected studies into an agreed template, recording where each value came from.
We agree the fields, outcomes and time points with you and pilot the template on a sample before completing the rest. We record where each value appears in the source, flag unreported data rather than assume it, and link multiple reports of the same study to avoid double-counting.
The quotation sets the number of studies and fields, and whether independent extraction by two people is included.
What you get

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.
