Performance of Classification Rules for People who Will Develop AKOA Over the Subsequent 4 Years

	Clinical Modela	Clinical + MRI Modelb
Specificity	0.82	0.90
Sensitivity	0.70	0.62
Explained Variance (%)	41%	39%

Note: AKOA = accelerated knee osteoarthritis, MRI = magnetic resonance imaging

^aThe final clinical classification tree included age, body mass index, serum glucose concentrations, femorotibial alignment angle, serum glycated serum protein concentrations, WOMAC knee-related function score, and coronal tibial slope angle [11]

^bThe final clinical+MRI classification tree included body mass index, serum glucose concentrations, effusion-synovitis volume, presence of cruciate ligament degeneration, and coronal tibial slope angle [11]
