Note the different units used for the measurement of each parameter for the 0 D stimulus (mm) and the mean changes during accommodation (µm). P values are the result of the LMM analyses for the fixed factors of accommodation stimulus and refractive error group, and the interaction between these factors. Significant P values are in bold font.
