Declarations

: TS, BK and UH are working at an independent, non-profit research institute, the Leibniz Institute for Prevention Research and Epidemiology – BIPS. Unrelated to this study, BIPS occasionally conducts post-authorisation safety studies (PASSs) requested by health authorities and financed by the pharmaceutical industry. These PASSs are performed in line with the ENCePP Code of Conduct, which means that the design and conduct as well as the interpretation and publication are not influenced by the pharmaceutical industry. The study presented was not funded by the pharmaceutical industry. MF is working at the Federal Institute for Drugs and Medical Devices (BfArM). BfArM is an independent higher federal authority within the portfolio of the Federal Ministry of Health in Germany. MF declares no conflict of interest.

: In Germany, the utilisation of health insurance data for scientific research is regulated by the Code of Social Law. All involved health insurance providers as well as the German Federal Office for Social Security and the Senator for Health, Women and Consumer Protection in Bremen as their responsible authorities approved the use of GePaRD data for this study.
: Informed consent for studies based on claims data is required by law unless obtaining consent appears unacceptable and would bias results, which was the case in this study. According to the Ethics Committee of the University of Bremen studies based on GePaRD are exempt from institutional review board review.
