Declarations
:
: The CPRD has obtained ethical approval from a National Research Ethics Service Committee (NRES), for all purely observational research using anonymized CPRD data; namely, studies which do not include patient involvement. The independent scientific advisory committee is responsible for reviewing protocols for scientific quality, but may recommend that study-specific ethical approval is sought if ethical issues arise in relation to an individual study. This study met the requirements under the CPRD obtained ethical approval from NRES. Only de-identified data were obtained, and patients could opt out if they did not wish to have their data used for research purposes.
