Blood samples and data that are registered about the patient only be used in accordance with the purpose of the study. On base line blood sample collected for BGL and HbA1c was discarded immediately after the analysis procedure. Similarly on the end-line survey blood samples will be discarded immediately after the test is done. All the data and samples are being processed without name, ID number or other directly recognizable type of personal information. A code number links the specific patient to his/her data and samples through a list of names. Only authorized project personnel have access to the list of names and be able to identify the patient. All data is stored in Services for Sensitive Data (TSD) server of University of Oslo. It will not be possible to identify individual patient in published or presented results from the study. All data will be discarded five years after the end of the project.
