Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
This study evaluated the efficacy and safety of canagliflozin in older patients with type 2 diabetes mellitus with inadequate control on their current diabetes treatment regimen. The study began on 07 June 2010 and ended on 23 May 2013. Patients were recruited from 90 study centers located in 17 countries worldwide.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
716 patients were randomly allocated to the 3 treatment arms. 714 patients received at least 1 dose of study drug and were included in the modified intent-to-treat (mITT) analysis set and safety analysis set. Participant flow is presented for Baseline to Week 26 but termed "Overall Study"; Week 104 data will be presented when available.
