Best regression model obtained for the use of cross-sectional data and specified input and output

Cross-sectional data
Given number	Input	Best regression (from 19 trained)	Output (at age)
1	Age, gender, sphere	GPR—Sq-exponential R2: 0.79 RMSE: 0.06 D	AxL/Cr
2	Age, gender, AxL/Cr	GPR—Matern R2: 0.78 RMSE: 0.87 D	Sphere

Axl/Cr, axial length to corneal radius ratio; D, diopter; GPR, Gaussian process regression; R², coefficient of determination; RMSE, root mean squared error; Sq-exponential, square exponential.
