For the sleep-related fatigue levels NO and HR, the distributions and slopes were analyzed for DP in the interval [2, 4]. In each cell, on the top, are the CCM means, respectively of NO and HR categories, and the p-value for the Wilcoxon rank test inside brackets, with the null hypothesis that the two levels of sleep-related fatigue have CCM values with the same distributions. On the bottom, are the slopes respectively of NO and HR values and the p-value for the F-test inside brackets, with the null hypothesis that those two levels have CCM values with identical slopes in their linear regressions. Simultaneous significant probabilities shift and trend changes between NO and HR levels are indicated by the gray background. See Figure 5 (top) to visualize plots of CCM from Frontal Midline to Parietal Midline areas.
