†p < 0.10

*p < 0.05

**p < 0.01

***p < 0.001. Wilcoxon rank-sum (Mann-Whitney) test were used for the sex difference in absolute importance and t-test for relative importance. We account for multiple comparisons of characteristics within the same group with Bonferroni adjustment (sets the significance cut-off at α/3). Setting the significance cut-off at α/9 (nine characteristics) returns the same conclusion. Effect size measures (Cliff’s delta (non-parametric) and Cohen’s d) are absolute value.
