Figure 1. — (A) Volcano plot of the distribution of differentially expressed proteins (DEPs) in E-ALF versus A-ALF. The x-axis shows log₂-transformed protein fold changes for human E-ALF versus A-ALF, the y-axis shows −log₁₀-transformed p-values. A total of 457 DEPs were identified, 217 being higher (red), and 240 being lower (blue) in E-ALF. (B) Principal component analysis of sample distribution. A-ALF (pink) and E-ALF (aqua) 95% confidence intervals (circles) and individual sample labels shown.
