Optimal Cut-Off Value of the Superior Articular Process Area as a Morphological Parameter to Predict Lumbar Foraminal Stenosis

<div>Receiver operating characteristic curve of superior articular process area for prediction of lumbar foraminal spinal stenosis. The best cut-off point of superior articular process area was 112.12 mm<sup>2</sup>, with sensitivity of 84.4%, specificity of 83.9%, and AUC of 0.94.<i> AUC: area under the curve</i>.</div>
