Significant differences between S_D, L_A and L_D in corresponding phases were calculated using one-way ANOVA followed by Bonferroni for individual comparison: * represents significant differences to S_D, ^# represents significant differences to L_A (p < 0.05). The number of data for each comparison are accessible in Supplementary Data⁵¹.
