Five-year attrition diagram demonstrates how patients were included and excluded in the 5-year cohort. Patients were included if they had any of the following: one inpatient claim with a diagnosis of type 2 diabetes, one prescription fill for diabetes medication, or two outpatient claims with a diagnosis of type 2 diabetes within 180 days. Only patients with an index diagnosis prior to 1 October 2010 were included to allow for 5 years of follow-up.
