Table 1. p-values for the different association tests (the LQ has been analyzed using an ANOVA, while handedness groups, handedness direction and degree of handedness have been analyzed using Kruskal-Wallis-tests).

Gene	SNP	LQ	Handedness groups	Handedness direction	Degree of handedness
LRRTM1	rs6733871	0.35	0.34	0.54	0.41
PCSK6	rs11855415	0.33	0.84	0.13	0.88
	rs9806256	0.89	0.77	0.69	0.43
	rs1947942	0.37	0.21	0.41	0.33
	rs10523972	0.02	0.0005*	0.07	0.001*

Effects significant at the p<0.0025 level (the adjusted p value for multiple comparision) are given in bold.

Note: * = p<0.0025 (Bonferroni corrected p value).

The p-values for all genotype group comparisons for LQ, handedness groups (consistent left-handers, inconsistent left-handers, ambidexter with a tendency towards left-handedness, ambidexter with a tendency towards right-handedness, inconsistent right-handers, consistent right-handers), handedness direction (left, right) and degree of handedness (consistent, inconsistent).
