Figure 5

ROC curves of predictive model and variable MMP-9 in elastic fibers. (a) The RF predictive model based on 5 variables as sex, age, deepness of granulomatous infiltration, MMP-9 IOD/area in elastic fibers, and pSTAT1 IOD/area in the nuclei of histiocytes showed an AUC of 0.9675. (b) MMP-9 in elastic fibers obtained an AUC of 0.9667.
