Figure 2

a) Significant correlation between age and PDS in females and males, b) significant correlations between age and hormones, as well as PDS and hormones in males, with only PDS and testosterone being significantly related in females. Pearson’s r values for age and hormone correlations, and Spearman’s r values for all correlations with PDS. Only youth with hormone values above the detection limit are included in the correlations. Graphs with testosterone have values on the left y-axis for girls, and right y-axis for boys.
