Comparison of genotypes on demographics

	Full sample		L-carriers		S-homozygots		p-value
	Mean	SD	Mean	SD	Mean	SD	p-value
Age (years)	28.39	8.38	28.62	8.21	27.31	9.39	0.574
DUP (% <3months)	46.59		47.30		42.86		0.760
Sex (% male)	58.70		57.89		62.50		0.734

N = 92 (76 L-carriers, 16 S-homozygots). DUP is duration of untreated psychosis (time from onset of symptoms to the first admission). P-values were computed with t-test (age) and chi-square test (sex and DUP).
