What graduate students and researchers say about Evidens's work.
I had the statistical analysis of my doctoral thesis done by the Evidens team. The work was finished in 2 weeks, with excellent quality of tables and charts. I recommend it to every graduate student!
Statistical analysis and help building the slides for my capstone project! Really great!
I'm grateful to Evidens for the quick help with my manuscript, with support on study design, methodology and statistical analysis (which I had no idea how to do...).

The most common questions from people hiring statistical consulting.
No. Evidens works as a methodological consultancy, without co-authorship. The authorship and the scientific responsibility remain entirely yours. We only suggest declaring the methodological assistance in the acknowledgments, if you wish.
Yes. Methodological and statistical support is a common and accepted practice in science. You remain the author and the party responsible for the project and for approval by the Research Ethics Committee. We deliver the method and analysis with transparency, so that you understand and can defend every result.
You upload the spreadsheet through the site itself. The identifiers (name, medical record number, ID number, dates) are removed in your own browser, before anything is sent — only the de-identified data reaches us, and it is never publicly exposed.
