Fig 1: ROC curves evaluating the diagnostic performance of raftlin and MDA in type 2 diabetes mellitus cases. (a) MDA: The AUC was 0.804, with an optimal cut-off value of 28.5 ng/ml (sensitivity: 68.8%; specificity: 86.4%). (b) Raftlin: The AUC was 0.839, with an optimal cut-off value of 130.0 pg/ml (sensitivity: 69.2%; specificity: 81.5%).AUC, area under the curve; MDA, malondialdehyde; ROC, receiver operating characteristic.
