Multivariate statistical analysis indicates the differentiation of patients from controls based on plasma lipidome profile: A principal component analysis as an unsupervised method discriminated patient groups from healthy controls. B Differences between HUA ≤ 40 vs. Gout ≤ 40 patients were represented by orthogonal partial least squares—discriminant analysis (OPLS-DA). C OPLS-DA distinguished HUA ≤ 40 and Gout ≤ 40 patients vs. controls shown with classification performance of 95% (D) of the model
