: All authors declare that they have no conflicts of interest.
: This article does not contain any studies with human participants or animals performed by any of the authors. The protocol for this study was approved by the Independent Scientific Advisory Committee (ISAC) to the CPRD on 1 August 2013 (ISAC reference number 13_124) with subsequent amendments approved by ISAC on 22 May 2014. Changes relevant to analyses presented here include identification of diabetes complications through the primary care record, as described above, rather than from hospital data; this change was made because hospital data linkage was not available in all patients. The ISAC protocol was made available to the reviewers and editors during the peer-review process.
