Respective box plots for a-wave amplitudes (a), b-wave amplitudes (c), a-wave (b) and b-wave implicit times (d) of the red cone response. In analogy to the scotopic response, with increasing stimulus intensity the a- as well as the b-red cone response got larger in the DTL electrode recordings compared to the Neuroline skin electrode recordings. A novel finding is the implicit time delay of the red a- and b-waves with the DTL electrode when compared to the recordings with the Neuroline skin electrode (Table 4). For all box plots, recordings obtained with a DTL electrode are plotted to the left, while recordings obtained with a Neuroline skin electrode are plotted to the right. The box length is the inter-quartile range. The line in bold depicts the median. Values between 1.3 and 3.0 box length represent outliers (open circles) and those with values more than 3.0 box length represent extremes (arrow heads). The respective p-values are shown on the top right hand side of the graphs (multivariate ANOVA)
