FIGURE 2.

Scatterplots for PC1–PC3 across age‐in‐months (years labeled for ease of interpretation) by sex, from top to bottom: PC1 (51.02%); PC2 (11.73%); PC3 (10.03%). Loess lines were added for sex with symbol shapes distinguishing males (circles; dashed line) and females (triangles; solid line). PC contours: dashed black outline represents example individual outlines along the represented axes. Solid yellow (minimum extremes) and blue outlines (maximum extremes) correspond to +/‐2SD shape variations captured by the EFA.
