HCP healthcare provider, n = number of HCPs in the specified category, N = number of HCPs in analysis population, PwD people with diabetes
Note: 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.
