Only significant results of MANCOVA are presented. Dependent variables: facial traits; independent variables: 1) BMI, 2) each of body parameters. Effect size (partial Eta²) and significance level (p) are presented only for each body parameter (after controlling for BMI). Definitions of the facial landmarks used for facial traits calculation can be found in Fig. 1. All presented associations stood significant after Bonferroni correction for testing 12 variables. Full results can be found in Supplementary Tab. 3
