Declarations
:
: These data were released under national statutory approvals from The Confidentiality Advisory Group (CAG): PIAG 1–05(c)2007, PIAG 3–06(f) 2008 and national ethical approvals from the Research Ethics Committee (REC): 13-LO-0610, 08-H1102–46. Data cannot be shared publicly because we do not own these data and are not permitted to share them in the original form. Data are available from the Clinical Practice Research Datalink (contact via ExternalRef removed) for researchers who meet the criteria for access to confidential data. There is a standard process for accessing this data where researchers need to get a scientific approval of their protocol by an independent scientific advisory committee (ISAC) of CPRD, sign a license agreement for data use and pay fees for the data. The authors did not receive any special privileges and applied for data access via the same route. The read code lists underlying the results presented in the study are available from the LSHTM Data Compass and are freely available for download from ExternalRef removed.
