This table shows the mean for each variable used in the regression model (excluding controls) by region and income category. High-income countries had a GDP > $15,000 while middle/low-income countries were below $15,000. All variables varied widely by region and income category. (MIR = Overall cancer mortality-to-incidence rate ratio, GDP = Gross Domestic Product per capita, THE = total health expenditure per capita, TEBD = Total external beam radiation devices per 100,000 population, Physician Density = Physicians per 100,000 population)
