## 3 Results  
The analysis included 1000 users out of a larger group of users with T2 DM who used the Dario platform between 2019 and 2021 and measured their blood glucose with at least three blood glucose measurements in the first and 12 th months. The group analyzed started from baseline average blood glucose >180 mg/dL and reported their race/ethnicity; ninety-seven percent of the users were located in the United States. Demographic characteristics did not differ between the WP and REM users for sex, major age group 45-65 (WP 59% vs. REM 62%), BMI groups, and insulin treatment intake (Table 1). Testing Differences in the Monthly Average Blood Glucose Levels throughout the Initial 12 Months for Different Races/Ethnicities  
No difference between WP and REM users in the average blood glucose at baseline was observed (Kruskal-Wallis test, \(p\) = 0.689). The blood glucose average was significantly reduced in all users and per racial/ethnic group over a year (Figure 1). All users reduced blood glucose by 14% (230 \(\pm\) 58 vs. 197 \(\pm\) 47) (\(p\) < 0.001); WP by 14% (229 \(\pm\) 58 vs. 197 \(\pm\) 47) (\(p\) < 0.001); REM by 15% (233.35 \(\pm\) 60 vs. 198.94 \(\pm\) 47) (\(p\) < 0.001) with the following reduction within each REM racial/ethnic group: Latino by 15% (237 \(\pm\) 59 vs. 202 \(\pm\) 48) (\(p\) < 0.001); Black by 15% (230 \(\pm\) 63 vs. 196 \(\pm\) 48) (\(p\) < 0.001), and Asian by 15% (229 \(\pm\) 55 vs. 195 \(\pm\) 43) (\(p\) < 0.005). The findings show that there were no differences in the glycemic outcomes achieved by several racial/ethnic groups using the same digital tool. Moreover, 27.3% (273 out of 1000) of all users reached an average blood glucose of less than and equal to 154 mg/dL equivalent to A1C 7.0% (Avg.bg mg/dL = 28.7 \(\times\) A1C \(-\) 46.7 by [PERSON] et al. [[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2742903/](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2742903/)]([https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2742903/](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2742903/)) (accessed on 13 December 2022). No differences in blood glucose averages between WP and REM were found at T\({}_{12}\) (Kruskal-Wallis test, \(p\) = 0.668) and no differences in monthly blood glucose averages among WP, Latino, Black, and Asian groups were found at T\({}_{1}\) and T\({}_{12}\) (Kruskal-Wallis test, \(p\) = 0.165/0.751, respectively). In addition, significant reductions in monthly average blood glucose were found in WP users and REM users in three categories of BMI levels (Figure 2). Furthermore, no differences between the dichotomic ethnicity were found at T\({}_{1}\) and T\({}_{12}\) within each BMI category (Kruskal-Wallis test, \(p\) = 0.994/0.988, respectively). \begin{table}
