a
The “Axial Length Stabilized at Baseline” cohort (n=19) and the “Axial Not Stabilized” cohort (n=48) were not included since parameters of axial stabilization were not available for these two groups.
b
Based on univariable ANOVA tests.
c
Adjusted estimates were based on a multivariable model with ethnicity and sex as covariates.
d
Based on the subset with parental myopia data (n = 225). Adjusted estimates were based on a multivariable model with ethnicity, sex and number of myopic parents as covariates.
