Figure 2. Adjusted Hemoglobin A_1c (HbA_1c) Levels by Follow-Up Care Modality and Baseline Insulin Regimen.

Adjusted 12-month HbA_1c changes are model-based estimates derived from linear mixed modeling of repeated measures of HbA_1c adjusted for patient age, sex, race, ethnicity, social deprivation index, rurality, baseline HbA_1c, and body mass index; patients were nested within practitioners. To convert to proportion of total hemoglobin, multiply by 0.01.
