  1. The data was described as mean ± standard deviation
  2. AL = axial length; D = diopter; DM = diabetic mellitus
  3. p for trend was measured using univariate regression analysis
  4. * Comparisons with the previous AL category using one-way ANOVA with Bonferroni correction
  5. Comparisons between the control group and the Type 2 DM group for each AL category using Student’s t-test
