Study design details

• Main study objective:
  To identify risk factors for severe hypoglycemic (SH) events in insulin-treated T2DM patients.
• Outcomes:
  Severe hypoglycemia
• Data analysis plan:
  For the primary and secondary objectives, a retrospective nested case-control study with incidence density sampling utilizing adjudicated healthcare administrative claims data will be used to identify risk factors of SH based on demographic and clinical characteristics in insulin-treated T2DM patients. Descriptive statistics will be reported using frequency and percentage distributions for categorical variables. Mean, median, and standard deviation will be generated as measures of central tendency and variance for continuous and count variables. Conditional logistic regression will be used to identify potential risk factors for SH after matching. Forward or backward variable selection procedures may be used to determine which variables to include in the final model.
