Can you calculate sample size before the study starts?

Yes. You receive the calculation, the assumptions behind it and the analysis plan wording for your protocol or ethics application.

What if our data cannot leave the hospital?

We can develop and test the analysis on a sample or a simulated dataset, then give you documented code to run on your own system.

Do you write the manuscript?

No. We provide the analysis, tables, figures and a technical record of every test. Your team writes the paper.

Data we accept

Anonymised data in Excel, CSV or SPSS, plus your protocol or research questions. For meta-analysis, your extraction sheet. We work with anonymised data only, and a confidentiality agreement can be signed before you share anything.

How a project runs

You share your study and the data you have.
You receive an analysis plan with the scope, timeline and a fixed price, agreed in writing before any work starts.
Quality control comes first, and any data problems are reported as they are found.
You receive figures, tables, documented code and a technical summary of every step, organised so you can rerun everything.

Analysis, figures and tables only; manuscript writing is not included.
