Secondary data
Secondary data are data that were already available before the current research project because they were originally collected for other investigation purposes. The NORAH Study on Health Risks is based, among other things, on Secondary data – in this case on pseudonymized patient data from health insurance companies – which already existed before the NORAH Study.
