Crude hair cortisol concentration distributions in AHEAD (n = 91) and CCC2000 (total sample (n = 1,450) and subgroup with a high physical symptom load (n = 147))

AHEAD Acceptance and Commitment Therapy for Health in Adolescents, CCC2000 Copenhagen Child Cohort 2000, pg/mg picograms/milligram. The figure shows the crude density plot for each sample. The crude medians were 2.2 (95%CI: 1.8, 2.7; IQR = 1.2-3.8) pg/mg in AHEAD, 2.1 (95%CI: 1.9, 2.1; IQR = 1.2-3.3) pg/mg in CCC2000 and 2.2 (95%CI: 1.9, 2.6; IQR = 1.3-3.5) pg/mg in the CCC2000 subgroup. The layout of the density plots has been modified to ensure that individual observations are unidentifiable. In accordance with this, high HCC values have been removed: for AHEAD and the CCC2000 subgroup, only HCC values between 0.0-9.0 pg/mg are shown (excluding ≤ 5 participants from each sample); for CCC2000, only HCC values between 0.0-10.0 pg/mg are shown (excluding 37 participants)
