Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
This study was conducted at 575 sites in 40 countries between August 22, 2003 and December 19, 2011. Three sites were closed and data from these sites were not analyzed following site audits and in compliance with rulings from national health authorities.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
The purpose of the factorial design was to efficiently answer two independent scientifically worthwhile questions regarding insulin glargine and omega-3 fatty acids within the context of a single clinical trial. Sample size was determined based on the insulin glargine study objective. Results reported below are those of the insulin glargine study.
