Contractual data analysis for researchers of the Medical Faculty at UZH
Statistical data analysis, plausibility checks, and interpretation of results can be performed by staff members of the EBPI if we have the capacity. Results of the analysis are summarized in a report .
The client and EBPI staff members responsible for the project discuss and finalize analysis plans. A non-binding cost estimate (based on an hourly rate of CHF 120 plus VAT) will then be sent to the client. The VAT will be removed from the bill if paid by the Institute/Clinic.
If the project goes to publication in a medical journal, staff members responsible for the project may be considered for co-authorship. Do not mention staff members in the Acknowledgments section of your paper, unless agreed upon.
Please refer to the
guidelines for preparing datasets for statistical analysis (PDF, 128 KB)(in German, update April 06, 2018).
The client has full responsibility for correct datasets, including backup, anonymization, and data protection.
Thesis/Dissertation Co-Supervision for Students of the Medical Faculty at UZH
Master’s theses and dissertations by students at the medical faculty at UZH can be co-supervised by staff members of the EBPI. If the supervisor of the thesis agrees on co-supervision, a «Vereinbarung Co-Betreuung» will be signed.
Some medical research questions may also be relevant to methodological research and may be suitable for scientific cooperation. The main goal of such a cooperation is to make scientific advances in both the methodological and medical fields, i.e., to produce research publications for both biostatistics/methodological journals and medical journals. In this case, the medical researcher and EBPI staff member should both be first authors.
Prerequisites for such a cooperation include joint grant applications, previous published projects, or corresponding research activities or interests.
Contractual data analysis for external researchers
External researchers should contact Eveline Bielser (administration).
