The double asterisk indicates subjects with myopia (CS1M) and without myopia (CS1NC) in the present study. The sharp (hash mark) indicates that the Chaoshanese mtDNA data were taken from a recent report [26]. The dagger indicates that R includes R*, R9b, R9c, and R11 and the double dagger indicates that M8 includes M8a, C, and Z.
