Distribution of ITGAV rs3738919 genotypes in Japanese rheumatoid arthritis patients and control individuals

	Genotype					C versus A		CC + CA vs. AA
	CC	CA	AA	Total	MAF	OR (95% CI)	Pa	OR (95% CI)	Pa
Patients	1,221	259	8	1,488	0.092	1.20 (0.91 to 1.60)	0.23	0.60 (0.16 to 2.72)	0.49
Controls	380	62	4	446	0.078

The distribution of the genotypes followed the Hardy-Weinberg equilibrium for both groups. ^aP values were obtained using Fisher's exact test (R version 2.4.1). CI, confidence interval; MAF, minor allele frequency; OR, odds ratio.
