The Effect of Corneal Refractive Power Area Changes on Myopia Progression during Orthokeratology

Table 2

Univariate and multiple linear regression analysis to determine the correlations between AL change and baseline age, baseline SER, decentration distance, and the different power areas.

	Univariate linear regression			Multiple linear regression
	B	β		B	β
Age (y)	−0.063	−0.329	<0.001	−0.055	0.015	<0.001
SER (D)	0.086	0.335	<0.001	0.066	0.021	0.002
Decentration distance (mm)	−0.325	−0.343	<0.001
Overcorrected area (mm^2)	0.022	0.194	0.037
Corrected area (mm^2)	0.046	0.234	0.011
Positive-power area (mm^2)	−0.091	−0.366	<0.001	−0.060	0.025	0.018

Note. AL: axial length; SER: spherical equivalent refractive power.
