Numbers of episodes per annum estimated using different approaches. Numbers of clinical cases; b incidence rate (episodes or cases per 100,000 person-year). Black points: based on EIR estimates calculated using Method A; yellow points: based on EIR estimates made using Method B with a common value for access to care (\(E_{14} = 0.15)\); blue points: based on EIR estimates made using Method B with country-specific values of \(E_{14}\)(blue). The diagonal line corresponds to a 1:1 relationship; the horizontal and vertical lines represent minimum and maximum ranges
