TABLE 2.

Curve-Based Estimates of Age and Axial Length at Stabilization and their Correlations Overall and by Baseline Age and Axial Elongation Status Group (N=364)^a.

	Overall n = 364	Younger Cohort n = 30	Older Cohort n = 334
	Mean (SD)	Mean (SD)	Mean (SD)	p value^b
Age at Stabilization (years)	16.3 (2.4)	16.5 (2.7)	16.2 (2.4)	0.56
Axial Length at Stabilization (mm)	25.2 (0.9)	25.5 (0.9)	25.2 (0.9)	0.11
Correlation between Age and Axial Length at Stabilization	0.44	0.48	0.44
*Pearson’s Correlation(p value)*	<0.0001	0.008	<0.0001	N/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.

Based on two-sample t-tests comparing means across three cohorts for the age and axial length at axial elongation stabilization.
