Important features identified by uni- and multivariate analyses. (A) G6PD− vs. control variable importance in projection (VIP) plot; colored boxes on the right indicate the relative concentrations of the corresponding metabolite in each group under current study. (B) Volcano plot showing the distribution of the fold changes in metabolite concentrations. Metabolites with absolute fold change >2 and adjusted p-value (FDR < 0.05) are indicated in pink. Comparisons were analyzed using Student’s t-test.
