Hazard ratio analysis for all-cause death

Number of obs = 163				LR chi2(3) = 69.67
No. of failures = 74				Prob > chi2 < 0.01
Survival time	Haz Ratio	z	P>|z|	[95% Conf. Interval]
IoMRI use	0.43	−3.20	<0.01	0.26, 0.72
E+	1.02	0.07	0.95	0.62, 1.66
High grade	13.62	5.03	<0.01	4.92, 37.69

IoMRI: intra-operative MRI; E⁺ : lesion location in eloquent brain area

IoMRI use and WHO high grade lesions were significantly associated with overall patient survival
