Swedish Twin Registry: For researchers
The Swedish Twin registry is an (inter)national resource. Data from the registry can become available to academic and industry-based researchers. Read more below what is required to initiate research with the Swedish Twin Registry.
KI has introduced a new web based application routine from August 18, 2020. See specific instructions for the Twin Registry on this page.
Regardless of the type of research interest, all potential collaborations or data access agreements must first be reviewed by the steering committee of the STR.
Application procedure to utilize the Swedish Twin Registry
Policy and conditions
The general conditions for collaboration with the Swedish Twin Registry can be found in our policy document. Start the process by reading the policy document so that all conditions can be met. The STR’s steering committee meets four times per year and decides on all requests.
In order to process your request, a complete application must be received by the STR no later than one week before a steering group meeting. For more information, please contact us by e-mail to firstname.lastname@example.org.

a) specific aims
b) general background (including relevant literature references)
c) requested variables with inclusion and exclusion criteria
e) description of the research group
- CV of the PI (Principal Investigator)
- Ethical application and ethical approval (for projects not including new contacts). For projects in which contacts with study persons are to be made, it is recommended that the STR steering committee reviews both contact letters and informed consent formulations before these documents are sent for ethical review.
Step 2: web application - NEW WEB BASED ROUTINE!
- Go to the new web based tool for core facilities, iLab, and register/login in the system.
