Summary:

      This randomized controlled, two arms, investigator initiated, intervention study is aimed to
      examine an investigational approach in contrast to the clinical standard of 1:1 dose basal
      insulin conversion in an attempt to lower the incidence and/or duration of hyperglycemia
      after transition from insulin pump to multiple daily injections in adults with type 1
      diabetes.
