DIABETES
The random allocation sequence (1:1) was generated by an experienced statistician at the German Diabetes Center (DDZ) (PB) using SAS software, version 9.3 (SAS Institute, Cary, NC, USA). Participants were randomly assigned to their treatment sequence by a person at the DDZ who was not involved in the conduct of the study. The randomisation list was kept by this person and was not accessible to the study personnel. Study participants, medical staff and researchers were blinded until completion of the study.
