N number of participants, SD standard deviation, mm millimetre, t-t tragus to tragus, t-ex tragus to exocanthion, t-sn tragus to subnasale, t-ch tragus to cheilion, t-gn tragus to gnathion. a, c, d, f = identical subscript letters have differences existing between the mean values of two tribes by means of a post hoc test (the p values are only the result of the ANOVA and not the post hoc test). Statistical significance level at p < 0.05
