Descriptive presentation of home versus childcare cortisol patterns by age group using raw (rather than model-estimated) data. Plotted values are averaged log-transformed midmorning and afternoon cortisol values. For home data, midmorning values across the two days were averaged to calculate a mean midmorning level, and afternoon values were averaged to create a mean afternoon cortisol level. For childcare data, cortisol values for midmorning and for afternoon were averaged across all 10 weeks in care. Averaged cortisol levels are plotted separately for infants (under 18 months; n = 42), preschool-aged children (18 months to 5 years; n = 92), and school-aged children (over 5 years old; n = 34).
