Latent factor loadings (median and 95% confidence intervals) of each predictor as identified by the two robust components of the group factor analyses. These analyses examined within and between variance in both perceived physical changes from the PDS as well as hormone levels in males (A, B) and females (C, D). These two latent factors capture the wide range of individual variability seen between physical and hormone metrics of early puberty among children, with latent factor 1 driven by hormone levels, and the latent factor 2 driven by physical maturation. Latent factor 1 accounted for 22.87% of variance of the pubertal measurements in (A) males and 31.16% in females (C). Latent factor 2 accounted for 15.77% of variance of the pubertal measurements in males (B) and 16.35% in females (D).
