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. |

| Measure Title | Number of Patients With Various Types of Symptomatic Hypoglycemia Events |
| Measure Description |
Symptomatic hypoglycemia was defined as an event with clinical symptoms consistent with hypoglycemia, based on data recorded in the participant’s diary. These were further categorized as confirmed (ie, with a concomitant home glucose reading ≤54 mg/dL [≤3.0 mmol/L]) or unconfirmed. Severe hypoglycemia was defined as an event with clinical symptoms consistent with hypoglycemia in which the participant required the assistance of another person, and one of the following:

| Safety Issue | Yes |
Population Description
| Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate. |

| The population analyzed was the safety population consisting of all randomized and treated patients (who received at least one dose of study drug) for the insulin glargine group and of all randomized patients for the standard care group. |
