Biostatistics Consulting

Biostatistics Consulting

In order to improve the quality of animal experimental research, we offer free biostatistical method consulting services to scientists, PhD students and master students of the UZH who conduct animal experiments. This includes advice on study design and sample size calculation, data analysis methods and reporting for publications, dissertations and theses. For Master students seeking advice, we recommend that the supervisor comes to the first meeting.

We also provide advice on applications for animal experiments (licenses and grants).

We encourage you to consult us during the planning phase of your study so that possible improvements can be made in research questions, study design and the absolute number of animals required (3Rs principles: reduction). Free of charge for UZH animal researchers (e.g. members of the Faculty of Natural Sciences, the Faculty of Medicine, the Vetsuisse Faculty, the University Hospital, competence centres, etc.).

The free 1h-consultation is per license (not per researcher or per group) in the case of "application for license to perform animal experiment in Kanton Zurich". Note that this 1h-consultation is NOT A VERIFICATION of experimental design & the planned statistical analysis of your application (new Form A, par 31).

In the moment we do not have capacity for the verification.

We use and promote the free software R. Unfortunately, we can only provide limited help with other statistical software. We also offer "contract consulting" and "contract data analysis" for internal and external researchers.
