Table 2.
Results of the pairwise comparisons (Wilcoxon signed rank test) for melatonin (in pg/mL), cortisol (in ng/mL) and sIgA (in μg/mL) levels between the morning after the baseline night and the morning after the recovery night for the dim and blue-enriched light condition. In bold results with p < 0.05.
