Figure 2. Adjusted Costs of Care for Types 1 and 2 Diabetes Estimated by 2 Cost-Estimation Methods in the United States, 2007–2014.

NOTE: Case-control design was used to estimate the cost difference in Method 1, where diabetes-related cost is the all-cause healthcare cost of diabetes minus the all-cause healthcare costs of their matched controls without diabetes; a code-based cost approach was used in Method 2, where diabetes-related cost is captured as the cost of healthcare services with diagnosis codes or pharmacy codes for diabetes and diabetes medications, respectively.
