Declarations
:
: The authors confirm that this study adhered to the Declaration of Helsinki. The CPRD has been granted generic ethics approval for observational studies that make use of only anonymised data and linked anonymised NHS health-care data (Multiple Research Ethics Committee ref. 05/MRE04/87). All CPRD studies require scientific approval from the MHRA Independent Scientific Advisory Committee (ISAC). The ISAC was established by the Secretary of State for Health in February 2006 to review the scientific merit of proposals for research using data from the CPRD as well as the Yellow Card Scheme database. This study’s protocol was approved and is registered as #19_219R. All the participants provided their informed consent and each individual GP practice participating in CPRD’s collection of their primary care data can choose to revoke their consent for data collection at any point. CPRD respects all patient opt-outs. Patients who have registered an opt-out will not be extracted for CPRD research or for data linkage. Researchers using the data must adhere to robust terms and conditions governing how the anonymized data is used.
