Bland-Altman plots for PIPR-mm (left) and PIPR-% (right) between the first summer sessions and winter assessments of the protocol with intensified blue light (550 µW/cm2) with a natural pupil (550My−). Differences between the two measurements (i.e., summer minus winter) are plotted against the mean of the two measurements. The dotted line represents the bias, i.e., the mean difference between all measurements of the summer and the winter.
