Studies using QALY/DALY indicators used to investigate the economic burden of stroke.

Study	Indicators	Objective	Result
Ock, et al. [3]	QALY	Estimating Quality-Adjusted Life-Year loss due to Noncommunicable Diseases in Korean Adults through to the year 2040	The largest QALY loss due to mortality was stroke (306,733), whereas the largest QALY loss due to morbidity was arthritis (502,513).
Persson, et al. [4]	QALY	To investigate whether the dependency of midlife stroke survivors had any long-term impact on their spouses’ QALY-weights.	Spouses of dependent stroke survivors (n = 50) reported a significantly lower mean QALY-weight of 0.69 in comparison to spouses of independent stroke survivors (n = 197) and spouses of controls, (n = 245), who both reported a mean QALY-weight of 0.77. The results from the regression analysis showed that the higher age of the spouse and dependency of the stroke survivor had a negative association with the spouses’ QALY-weights.
Sudharsanan, et al. [5]	DALY	To directly estimate disability-adjusted life years (DALYs) lost due to stroke in rural Gadchiroli, India and measure the contribution of mortality and disability to total DALYs lost.	229 stroke deaths among the total population of 94,154 individuals and 175 stroke survivors among the subpopulation of 45,053 individuals. An estimated 2984 DALYs were lost due to stroke per 100,000 person-years, with a higher burden among men compared with women (3142 vs. 2821 DALYs). Over three-fourths (80%) of the total DALYs lost due to stroke were between the ages of 30 and 70 years. YLL accounted for 98.9% of total DALYs lost.
