Sample Size Determination and Data Source
- The research question was – Does SGLT2i therapy for T2DM increase risk of UGIs?
-
Primary hypothesis - the use of SGLT2 inhibitors is associated with increased risk of UGIs
- ○
- Ha = IE > INE ± 4%
-
Null Hypothesis – There is no difference between the risk of UGIs in SGLT2i-exposed population and unexposed population
- ○
- H0 = IE – (INE ± 4%) = 0
-
Secondary Hypothesis the increased risk, if any is directly influenced by the dosage of the drug
- ○
- H1 = IEn > IEn+1
