Visualization of the distribution of COVID-19 serum lipidomics data. A) The concentration of lipids was normalized by averaging the replicates and normalizing the means in each analyzed condition (mild, moderate, severe) for each lipid class. B) The total amount of each lipid class was calculated as the sum of the lipid concentrations within that class, and divided by the number of patients included in each experimental condition. The increasing or decreasing trend for each lipid class can be observed in mild, moderate and severe patients. C) Pie chart describing the composition of the lipid panel analyzed by MS-MRM-based lipidomics, with detail of the number of analytes for each class.
