Prediction accuracy, sensitivity, and specificity using three combination of morphological risk factors according to three measurements of plaque progression from IVUS + OCT, IVUS50, and IVUS200 models. Com.1 is a combination of WT, LA, PA, and PB. Com.2 is a combination of mean cap thickness, min cap thickness, WT, LA, PA, and PB. Com.3 is made of a combination of 14 morphological risk factors used in this study.
