From: The pupillary light reflex (PLR) as a marker for the ability to work or drive – a feasibility study
Boxplot of the PLR parameters contraction velocity, latency, half dilation time, and the PVT that were significant in the one-way ANOVA. For each parameter, minimum, first quartile (Q1), median, third quartile (Q3), and maximum were illustrated in dependence of the exposure (baseline vs. sleep deprivation vs. alcohol exposure). Statistically significant differences between the different types of exposure were indicated
