Light grey box plots: monthly morning median cortisol value, inter quartile range one and three.
Dark grey box plots: monthly evening cortisol median value, inter quartile range one and three. *** = P<0.000 significant difference between evening and morning cortisol, Wilcoxon’s rank-sum test, month one to twelve.
Fig 2.
Individual CCR development, arbitrarily defined based on accuracy of the method, in the 68 infants with analyzed morning and evening cortisol concentrations for all 13 months.
White squares: "CCR positive" (Ratio: evening/morning cortisol <0.80). Black squares: "CCR negative" (Ratio: evening/morning cortisol >1.20). Gray squares: neither "CCR positive" nor "CCR negative" (Ratio: evening/morning cortisol 0.80–1.20). One column represent each month. Each row represents one infant (68 infants).
