Table 6 Multivariate logistic regression analysis of lymph node metastasis in early gastric cancer

Factor	OR (95%CI)	P-value
Lesion size		0.025
Middle lesion size (20-30 mm)	1.230 (0.774, 1.955)	0.380
Large lesion size (>30 mm)	1.900 (1.197, 3.015)	0.006
Histology		0.049
Sig	1.146 (0.698, 1.881)	0.590
Muc	2.823 (1.225, 6.505)	0.015
LVI	15.702 (10.405, 23.695)	< 0.001
Invasion depth		< 0.001
SM1	2.285 (1.317, 3.965)	0.003
SM2	3.230 (2.006, 5.201)	< 0.001

SM1: Invading the superficial (<0.5 mm in depth) submucosa. SM2: Invading the deep (> 0.5 mm in depth) submucosa. LNM: Lymph node metastasis; OR: Odds ratio; CI: Confidence interval; LVI: Lymph-vascular invasion; Sig: Signet ring cell carcinoma; Muc: Mucinous adenocarcinoma.
