Figure 2. Incidence Rate Ratios of Severe Hypoglycemia and Diabetic Ketoacidosis for Pump Therapy vs Injection Therapy.

Figure 2.

Incidence rate ratios and 95% CIs are presented to show the risk of severe hypoglycemia, hypoglycemic coma, diabetic ketoacidosis (pH <7.3), and severe ketoacidosis (pH <7.1) in patients using insulin pump therapy compared with the risk in patients using insulin injection therapy. Error bars indicate 95% CIs. A, Analysis in the propensity score–matched cohort including 9814 patients using injection therapy and 9814 patients using pump therapy. B, Analysis with propensity score inverse probability of treatment weighting of the entire cohort (16 460 patients using injection therapy, 14 119 patients using pump therapy). Estimates are derived from negative binomial regression analyses.
