Tumor markers and multimodal magnetic resonance imaging in predicting rectal cancer stage and differentiation

Table 3 Consistency between magnetic resonance imaging and clinical pathological examinations in the diagnosis of T-stage of rectal cancer

MRI staging	Pathological staging (gold standard)		Total (n)
	T1-T2	T3-T4
T1-T2	60	6	66
T3-T4	5	38	43
Total (n)	65	44	109

P < 0.001. Consistency statistics: Cohen’s κ = 0.789 (95% confidence interval: 0.692-0.886). Agreement level: Substantial. MRI: Magnetic resonance imaging.
