A) Comparison of mean choroidal thickness between control and PD participants, correcting for age, sex, axial length, distance from fovea, and quadrant. B) Subregion analysis comparing control and PD participants using a mixed effect model correcting for age, sex, and axial length. Shaded/Bolded boxes represent significance (p<0.05). C) Effect of PD status on choroid thickness in each quadrant (or distance) using a mixed effects model correcting for distance (or quadrant), age, sex, and axial length.
