	Coefficient of Preference of the Signal (RSn)
	Mean ± SD	Min/Max	t	P
Female	0.149 ± 0.392	−1.000/1.000	2.178	0.037
Male	0.128 ± 0.314	−0.333/0.667	2.309	0.028

Each individual was free to choose between saliva with (+/+ genotype) or without (−/− genotype) A27 and BG27. Mean ± SD, minimum and maximum values, and one-way t-test statistics are presented separately for males and females. Max, maximum; Min, minimum.
