Prognostic value of histology and MR imaging features in predicting survival outcomes, with discrimination performance

Feature	HR (95% CI)	p value*	C-index (95% CI)	p value†
RFS
Pathology (LD type)	2.4 (1.5–3.8)	<0.001	0.597 (0.545–0.649)	(−)
Two or more imaging features	2.0 (1.2–3.6)	0.013	0.543 (0.506–0.580)	0.046

Pathology (LD type)	3.0 (1.8–5.2)	<0.001	0.631 (0.568–0.694)	(−)
Two or more imaging features	2.2 (1.2–4.1)	0.012	0.550 (0.501–0.599)	0.010

HR, hazard ratio. * p values were obtained from the log-rank test.

^†p values were obtained from the comparison of C-index between the pathology (LD type) and two or more imaging features.
