Only data that had previously been collected as part of clinical care was extracted from the medical notes and only members of the patient’s direct clinical care team had access to the medical records. Informed consent was waived as there was no data collected over and above the existing medical records. Data was anonymised such that individual patients were not identifiable. All experiments were performed in accordance with the relevant guidelines and regulations (e.g. Declaration of Helsinki).
