Mean of daily productivity loss cost.
The exchange rate of Korean won to the US dollar was 1086.3 Korean won/US dollar in 2020. The mean and standard deviation of each cost is presented in the graph. Migraine is defined as respondents who met all three modified ICHD-2 criteria. Probable migraine is defined as respondents who met two of three modified ICHD-2 criteria.
