To the Editor A recent study by Dr Karter and colleagues concluded with a difference-in-differences framework that “insulin-treated patients with diabetes selected by physicians for real-time continuous glucose monitoring (CGM) compared with noninitiators had significant improvements in hemoglobin A1c and reductions in emergency department visits and hospitalizations for hypoglycemia.”1 The Discussion noted that there were minor but statistically significant increases in the number of telephone visits and a decrease in outpatient visits. However, according to the article’s Table 3, the difference of outpatient visits between CGM initiators and noninitiators with type 2 diabetes did not achieve statistical significance.
