Table 4. Association between APOE ε2 and gastric cancer subtype.

Gastric cancer subtype	Single variable analysis		Multivariable analysis
	OR (95% CI)	P-value	OR (95% CI)	P-value
Intestinal	1.41 (0.94, 2.11)	0.10	2.01 (1.13, 3.56)	0.017
Diffuse	1.51 (1.00, 2.27)	0.051	2.86 (1.57, 5.21)	0.0006

OR = odds ratio; CI = confidence interval. ORs, 95% CIs, and p-values result from logistic regression models. Multivariable models were adjusted for all variables that were associated with risk of overall gastric cancer in single variable analysis with a p-value of 0.10 or lower, which were age, BMI, triglycerides, total cholesterol, HDL-cholesterol, LDL-cholesterol, ApoA1, ApoB, and ApoA1/apoB ratio.
