SGLT2 Inhibitor Risk of Below-Knee Lower Extremity Amputation: A Retrospective Cohort Study Using a Large Claims Database in the United States
The purpose of the study is to estimate the incidence of below-knee lower extremity amputation in type 2 diabetes mellitus (T2DM) participants newly exposed to sodium-glucose co-transporter 2 inhibitors (SGLT2i)/ non-SGLT2i antihyperglycemic agents (AHA) overall and in the subgroup with high cardiovascular (CV) risk and to compare the hazards of below-knee lower extremity amputation in canagliflozin new users versus non-SGLT2i AHA new users.

Study Population
Participants who are new users (with at least 365 day of prior observation) to a drug exposure of interest between April 1, 2013 and January 31, 2015 and at least 1 condition occurrence of 'Type II diabetes' any time before or on index and no condition occurrences of 'Type I diabetes' or 'Secondary diabetes' any time before or on index date.
January 31, 2015 reflects the data cutoff date for the initial analysis.
Description
Inclusion Criteria:
- First exposure to the particular drug in person's history
- For the initial analysis, exposure start is between April 1, 2013 and January 31, 2015. For the ongoing repeat analysis per the protocol amendment, the study period ending date will vary depending on the time of each data extraction and analysis
- At least 365 days of observation time prior to index
- At least 1 condition occurrence of 'Type II diabetes' any time before or on index
- Exactly 0 condition occurrences of 'Type I diabetes' any time before or on index
Exclusion Criteria:
- Participants who had amputations prior to the index date were excluded.
