Involvement of SLC39A6 in gastric adenocarcinoma and correlation of the SLC39A6 polymorphism rs1050631 with clinical outcomes after resection

Table 3 Chi-square partitioning to test the association between SLC39A6 rs1050631 and SLC39A6 expression detected by immunohistochemistry

SNP	Genotype	expression of SLC39A6		Case-total^a	Case-case^b
SNP	Genotype	Low(n)/ High(n)	High expression rate (%)	p < 0.00833	p < 0.0125
Total(n = 198)		112/86	43.4
rs1050631	CC	61/31	33.7	0.116	1vs2:0.005
	CT	42/50	54.3	0.083	2vs3:0.422
	TT	8/6	42.9	0.966	1vs3:0.712

^aCase–total: p value for the comparison between the group with the indicated genotype and the total group of 198 samples;
^bCase–case: p value for the pairwise comparisons between groups with different genotypes
