Fig. 2. Change of HbA1c from baseline to end of follow-up in study participants at different usage patterns compared with controls.

¹Estimated differences of study participants minus matched controls are presented as means (95% CI). ²Change of HbA1c when the tool was used at least every other month in participants with MOD characteristics compared with matched controls with MOD. A total of 32%, 28%, 33% and 21% of participants using the tool at least biweekly, monthly, bimonthly, and non-users, respectively, had MOD. ³Plots of mean HbA1c difference between participants and controls with 95% confidence intervals.
