Overfeeding-induced changes in individual plasma ceramides in the groups. Each square in the heat map indicates the log₂ of the ratio between mean concentrations after vs. before for an individual ceramide. The color key denotes the relationship between the color of the heat map and log₂ of the ratio between the means, with 0 indicating no change. The y-axis denotes the fatty acyl chain structure (number of carbon atoms:number of double bonds), and the x-axis indicates the sphingoid base species. *P < 0.05; ***P < 0.001.
