Study of Correlation between MRI Morphology of Primary Tumor and Extramural Vascular Invasion in Rectal Cancer

Table 2

Results of imaging and pathologic factors in multivariate logistic regression analysis.

Independent predictor	Odds ratio	95% CI	P value
NP	11.566	3.00–44.65	<0.001
PLN	7.027	1.62–30.55	<0.001

95% CI: 95% confidence interval; NP: nodular projection at the primary tumor’s edge; PLN: pathology-proven local node involvement.
