Table 2. Association between NoV GII.3 and GII.4 Infections and Secretor Genotypes.

Secretor genotype	No.	GII.3*			GII.4#			GII.3 +GII.4†
		(+)	%	P	(+)	%	P	Pos (%)	P	Odds Ratio (95% CI)
SeSe(AA)	60	6	10.0	0.668	9	15.0	0.275	15(25.0)	0.1	3.3 (0.7- 16.0)

Total	124	16	12.9		18	14.5		34(27.4)

When compared SeSe + Sese with sese, the two-tailed Fisher exact test was used. Unadjusted crude odds ratio was estimated.

^*P = 0.3 for GII.3

^#P = 0.193 for GII.4

^†P = 0.03 for GII.3 + GII.4
