Predictors of level of sporting performance (Study 1).

	Odds Ratio (95% confidence interval)
Mixed-handed	0.77 [0.53–1.11]
Left-handed	0.97 [0.80–1.18]
Mixed-footed	1.38 [1.20–1.58]∗∗∗
Left-footed	1.19 [0.96–1.47]
Control variables : Sex (male)	2.05 [1.20–3.48]∗∗
Age	0.97 [0.97–0.98]∗∗∗
Sample	1.06 [0.94–1.20]

Analysis n = 12403. Right preferences served as reference categories for effect tests of handedness and footedness. Significant effects (p < 0.05) are printed boldface. The model included also interaction terms for lateral preferences with sex, and for mixed-footedness with sample, which were not significant and are not shown for brevity (see Section “Associations with Sporting Performance” of Study 1). ^∗∗p < 0.01, ^∗∗∗p < 0.001.
