From: Novel lipidomes profile and clinical phenotype identified in pneumoconiosis patients
The lipid classification of differential metabolites. The proportion (%) of 11 main lipid elements of healthy controls (a) and pneumoconiosis (b). Volcanic map (c) between healthy controls with pneumoconiosis. The abscissa represents log values of fold changes, where the left side of the first dotted line perpendicular to the abscissa represents < 2/threefold changes (down-regulation) and the right side of the second dotted line represents > 1.5-fold changes (up-regulation). The vertical coordinate represents –log10 (P-value). The upper side of the dotted line perpendicular to the ordinate stands for P-value less than 0.05, as compared with healthy controls
