Results of multiple regression analyses to estimate the association between myopia and total ocular higher order aberrations (evaluated with natural pupillary diameters, average value φ = 6.1 mm).

D diopters, SA spherical aberration, S3 3rd-order aberrations, S4 4th-order aberrations, THOA sum of the 3rd- to 6th-order aberrations, 95% CI 95% confidence interval, β coefficient. Two multiple regression models were used. Axial length or cycloplegic objective refraction was used as the outcome variable. P < 0.05 are highlighted. For gender, boys were numbered 1 and girls were numbered 0.
