Compared to sTWEAK alone, ROC curve analysis of the sCD163/sTWEAK ratio in patients with dilated cardiomyopathy increased neither sensitivity nor specificity for the prediction of death/heart transplantation or clinical deterioration on follow-up (P = 0.650 for death/heart transplantation and P = 0.099 for clinical deterioration). Here, CD163 is linked to dilated cardiomyopathy.
