Model Logic Flow. Schematic overview of the methodology to estimate key measures. Step 1: collect information on incidence ratio and average years lived. Step 2: determine prevalence per country/region and disease type. Step 3: using additional population data, determine the patient pool per country/region and disease type. Step 4: estimate the patient pool per genetic subtype and age group for each country/region. Step 5: sample data visualizations of results from key countries and regions
