Graph showing the correlation coefficient according to corneal power. The correlation coefficients (Y-axis) of each cumulative subgroup (X-axis), which contained subjects whose corneal power was less than the corneal power on the X-axis, are shown as a graph according to the increase of corneal power from 42 D (heavy line). The correlation coefficient of each cumulative subgroup, which contained subjects whose corneal power was greater than or equal to the corneal power on the X-axis, are shown as a graph according to the decrease of corneal power from 47 D (light line). β = Correlation coefficient
