Table 5. Crossover analysis of interaction between BMI and rs4305.

BMI	Allele	Case	Control	P Value	OR	95% CI
<25	G	581	876	1	1	NA
≥25	A	300	172	<0.001	2.63	2.12–3.26
≥25	G	460	270	<0.001	2.57	2.14–3.09
<25	A	451	484	<0.001	1.41	1.19–1.66

The P values were obtained from the comparison of two allele frequencies. OR, odds ratio; CI, confidence interval.
