Data are means (SD). Patients with and without discontinuation were propensity score matched for age, sex, diabetes duration, diabetologist care, disease management program participation, and Charlson Comorbidity Index; cost differences were further adjusted for baseline costs and HbA1c. ID, index date of starting basal insulin therapy. Cost difference (last column): positive values represent savings; negative values are excess expenditure.
P values: difference (glargin versus NPH) of costs differences (post/prior ID).
