Unit: 1,000 Korean won; All costs are presented in 2008 Korean currency value (1,200 Korean won = 1 US$); ^a SMR: standardized mortality ratio of non-stroke mortality among people with prior stroke versus general population (Base-case values are 1.914 for males and 2.295 for females. Sensitivity analyses were performed using the base case value of SMR ± 20%); ^b Cost of illness refers to costs of treating non-fatal stroke (costs in first year and second year), costs of treating fatal stroke, and costs of premature death.
