How to compare AUROC of the models fitted by SVM in Biomarker analysis?

In Biomarker analysis ->multivariate->explore, SVM provided me with 5 models with their AUC and 95%CI. I tried to compare them with z test, but it seemed the 95%CI were binomial exact confidence interval, which DeLong method cannot be applied to. Do we have any way to compare those AUC?

Currently MetaboAnalyst is not supporting statistical comparison of the models on this page. However, if you find a good method, you are welcome to suggest it (with related papers / links) - we will consider adding support in a new release, together with the associated documentations.
