Multiple linear regression analysis on AL difference and refractive error.

Variable	Estimate	Standard error	95% CI	value
Intercept	6.094	2.504	(1.093, 11.096)	0.018
Age (years)	−0.078	0.037	(−0.152, −0.004)	0.040
Flat-K in myopic eye	−0.122	0.055	(−0.231, −0.013)	0.029
Flat-E in myopic eye	−1.418	0.795	(−3.005, 0.169)	0.079
Baseline AL difference (mm)	−1.627	0.147	(−1.921, −1.333)	<0.001

The adjusted R² was 0.705.
