Who this is for

Most doctors who contact us are not stuck on the medicine. They have the data and no statistician down the corridor.

Faculty with a dataset

You have collected the cases for an original article or case series, and the analysis is the step that keeps slipping.

Consultants in private practice

A clinical audit or retrospective review is sitting in a spreadsheet, and there is no research office to hand it to.

Authors facing reviewers

A reviewer has asked for a different test, a subgroup analysis or confidence intervals, and you need it redone properly.

Researchers at the planning stage

You need a defensible sample size before the ethics committee meeting, not after.

Which statistical test does your study need?

The right test depends on your question and on what your data look like. This is the reasoning we write down for you, so you can explain it at a viva, a department meeting or to a reviewer.

Questions doctors ask us

How long does statistical analysis take?

7 days from the point we have your cleaned, de-identified dataset and your study objectives.

Do you use SPSS or R?

Both. We use whichever suits the analysis and tell you which software and version produced each result, so your methods section is accurate.

What data do I need to share?

Your dataset in Excel, CSV or SPSS format and your study objectives or protocol. Remove patient names, phone numbers and hospital IDs before you send it.

Can you calculate the sample size before I start?

Yes. Sample size calculation is available on its own for ₹1,999, and it is worth doing before you apply for ethics approval.

What if a journal reviewer asks for more analysis?

Revisions are unlimited, including reanalysis after reviewer comments. A written point-by-point reviewer response letter is available separately from ₹3,999 per round.
