From: Circulating metabolite profiles to predict response to cardiac resynchronization therapy
Quantification of the diagnostic performance of the metabolite panel containing Isoleucine, Tryptophan and Linoleic acid in discovery set (a) and validation set (b). The optimal cutoff value was obtained (0.5276) and applied to evaluate the prediction capacity of the current model. In validation set, QRS duration (orange curve) has an AUC of 0.643 (95% CI: 0.486–0.799) and metabolic panel (blue curve) has an AUC of 0.929 (95% CI: 0.864–0.994)
