Declarations
:
: The Medical Ethical Committee of the Erasmus MC examined the study protocol and issued a waiver for the Medical Research Act (in Dutch: Wet medisch-wetenschappelijk onderzoek met mensen (WMO)) (MEC-2016–041), so no formal consent was needed. All patients undergoing treatment at our center are informed that pseudonymized data may be used for retrospective research and patients have the opportunity to object to this. Patients that objected were excluded from the analysis.
: Not applicable
: The authors declare that they have no competing interest.
