Fig. 2From: Circulating metabolite profiles to predict response to cardiac resynchronization therapyOPLS-DA analysis. a OPLS-DA score plot of the discovery set samples. b Validation plot of the model obtained from 99 permutation tests. c T-predicted scatter plots of the OPLS-DA model. Solid circles and squares represent non-responders and responders to CRT in the discovery set; hollow circles and squares represent non-responders and responders to CRT in the validation setBack to article page
