Bar plots show the mean global health (QOL) utility. Post hoc comparisons of global QOL (a) and utility (b) among different groups of annual family income (classified into > 1,000,000, between 1,000,000 and 500,000 and < 500,000 NTD). The results reveal that a lower annual family income yielded a lower global QOL and utility compared with the other groups
