Declarations
:
: This study was approved by the hospital Quality Governance department on 1 October 2019. The study was conducted as service evaluation and registered with the Royal Free London NHS Foundation Trust under service evaluation and audit (Ref: 225025). The study was assessed with the UK Policy Framework for Health and Social Care Research (2020) in mind and assessed with the UK Health Research Authority decision tool and was deemed to not fit the criteria of a research study requiring an ethical opinion. The study was discussed with the Royal Free London NHS Foundation Trust Research and Development office and judged to be a service evaluation/audit not requiring review by a UK Research Ethics Committee. All methods were performed in accordance with the Declaration of Helsinki and with hospital’s guidelines and regulations. As part of routine clinical care, patients provided informed consent for obtaining images and samples. Only anonymised data were used in this study and, due to the retrospective study design, written informed consent from the patients was waived by the hospital Quality Governance department in line with the hospital's policy on service evaluation and audit.
