	Unstandardized Coefficients B (SE)	Standardized Coefficients β	t	P value
Administration of atropine	– 0.052 (0.020)	– 0.230	– 2.536	0.016
Age at baseline	– 0.026 (0.006)	– 0.402	– 4.538	< 0.001
Change of ChT	– 0.003 (0.001)	– 0.363	– 3.760	0.001
Change of RT-Whole	– 0.018 (0.004)	– 0.440	– 4.559	< 0.001
Intercept	0.405 (0.058)		6.957	< 0.001

The coefficient of determination (R²) was 0.734

ChT choroidal thickness, and RT-Whole means the overall average of retinal thickness
