HCP-Estimated Proportion of PwD who a) Missed/Skipped or b) Mistimed 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 1 and Supplementary Table 2. Within the ≤ 30% category, HCP estimated that the proportion of PwD with optimal dosing who did not (a) miss or skip any doses constituted 22.2% for basal T1D, 9.2% for basal T2D, 13.6% for bolus T1D, and 6.7% for bolus T2D, while those who did not (b) mistime any doses constituted 18.6% for basal T1D, 10.9% for basal T2D, 11.1% for bolus T1D, and 6.9% for bolus T2D. HCP estimates were for their impression of the proportion of PwD with suboptimal dosing in the past 30 days not due to skipping a meal
