Axial length growth and RCRP calculated from mean values in each section. (A) Scatter plot illustrating the relationship between Vmax and axial growth. Growth >0.25 mm (red) is considered a weak myopic control effect and growth smaller than 0.25 mm (blue) is considered a clear myopic control effect. (B) There was no difference in the M values between the weak and clear groups. (C) Subjects in the weak group had significantly smaller amplitudes of F1 and F2. (D) Logistic regression showing the probability of having clear myopic control increases with the value of Vmax. (E) Threshold to have a >80% chance of achieving clear control effect. (F) Logistic regression using different amounts of axial growth as the criteria of clear control. As along as the criterion was >0.25 mm, the logistic regressions are significant.
