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.
All randomized participants who received at least 1 dose of study drug.

Reporting Groups
  Description
Insulin Lispro / Insulin Aspart Insulin lispro [100 units/milliliter (U/mL)] administered by continuous subcutaneous insulin infusion (CSII) pump for 16 weeks in Treatment Period 1, followed by insulin aspart (100 U/mL) administered by CSII pump for 16 weeks in Treatment Period 2.
Insulin Aspart / Insulin Lispro Insulin aspart (100 U/mL) administered by CSII pump for 16 weeks in Treatment Period 1, followed by insulin lispro (100 U/mL) administered by CSII pump for 16 weeks in Treatment Period 2.
