Table 4:

AUROC for predicting surgery using each quantitative metric on the prognostic cohort (n = 58)

Metric	Predicting Surgery at Each Spinal Level
Metric	AUROC	95% CI	Significance^{^a}
DSCA	82.4	(75.5–90.4)	P = 1.0
DSDIA	81.3	(73.2–89.4)	P < .001
DDRDIA	80.8	(73.0–89.5)	P < .001
DDRCA	83.5^{^b}	(76.6–90.1)^{^b}	P < .001^{^b}

↵a The P values represent comparison between each metric and AUROC obtained with the baseline metric DSCA.
↵b Quantitative metric with the highest AUROC.
