Performance of the ML Model for Reclassifying Rapid Plaque Progression Over Duke CAD Risk Score in Symptomatic Patients

	cNRI	95% CI	P Value	% Event Classified	% Nonevent Classified
Over Duke CAD risk score in symptomatic patients
ML model 1	0.21	−0.08 to 0.48	0.151	−5%	26%a
ML model 2	0.56	0.28 to 0.84	<0.001	15%a	41%a
ML model 3	0.85	0.57 to 1.13	<0.001	21%a	64%a

CAD indicates coronary artery disease; cNRI, category‐free net reclassification index; ML, machine learning.
