  1. Adjusted for all variables listed. R2 for high myopes: 0.129; R2 for moderate myopes: 0.033; R2 for −2.00 D~−3.00 D: 0.083; R2 for −2.00 D~−1.25 D: 0.062; R2 for −1.25 D~−0.50 D: 0.075.
  2. BMI: body mass index; AL: axial length; IOP: intraocular pressure; CI: confidence interval; D: diopter.
  3. High myopia and moderate myopia was defined as spherical equivalent ≤ −5.0 D, −5.0 D < spherical equivalent ≤ −3.0 D, respectively.
