Serum metabolic profile displayed differential metabolic features in young adults with CAP as compared to normal control. (A) 2D projection plots of metabolites from PLS-DA analysis, indicating clear separation between the young CAP and control. (B) Variable importance in projection (VIP) of metabolites and their ratios of biological significance. (C) Heatmap of the significantly altered metabolites and their ratios of biological significance in the young CAP and control.
