HCP-Estimated Proportion of PwD who Miscalculated Their Insulin Doses. HCP = healthcare provider; PwD = people with diabetes; T1D = type 1 diabetes; T2D = type 2 diabetes. Note: Percentages may not total 100% due to rounding. The ≤ 30% category comprises the none, 1–10%, 11–20%, and 21–30% subcategories; the 31–70% category comprises the 31–40%, 41–50%, 51–60%, and 61–70% subcategories; and the ≥ 71% category comprises the 71–80%, 81–90%, and 91–100% subcategories. Individual subcategories are presented in Additional File 2, Supplementary Table 4. HCP estimates were for their impression of the proportion of PwD with suboptimal dosing in the past 30 days. Within the ≤ 30% category, HCPs estimated that the proportion of PwD who had no challenges in achieving optimal dosing due to calculating doses was 23.9% for basal T1D, 15.0% for basal T2D, 11.3% for bolus T1D, and 5.8% for bolus T2D
