The coefficient of determination (R²) for each parameter is shown for the CSA group and the LA group separately. The simplified measurements are listed in the upper half, whereas the automated measurements collected from the OCT devices are shown in the lower half.

^*For the longitudinal group measurements are given as change from the previous visit.
