Table 3.

Observed average change in asymmetry and status of the better eye relative to baseline from univariate models. A positive change in asymmetry indicates increasing asymmetry. A positive change in the better eye indicates the eye declined for logMAR and corneal curvature. A negative change in spherical equivalent indicates increased myopia.
