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