Comparison of Two Approaches to Insulin Therapy in Patients With Type 2 Diabetes (IOOX)
Comparison of Two Approaches to Basal-Bolus Insulin Therapy in Patients With Type 2 Diabetes and Inadequate Glycemic Control on Oral Therapy: Comparison of Premixed Insulin Lispro Mid Mixture With Separate Basal and Bolus Insulin Injections
A study of patients with type 2 diabetes and inadequate glycemic control on two or more oral antihyperglycemic agents comparing adding insulin lispro mid mixture to the oral antihyperglycemic agents to adding insulin glargine to the oral antihyperglycemic agents.
