Figure 6. Correlation plots of protein levels correlated with CST. All data points of the relative abundance of protein levels as determined by mass spectrometry are plotted against the corresponding CST values of each patient. A best-fit linear regression line with 95% confidence bands (dotted line) is shown. Protein levels are presented as log₂-transformed label-free quantification units (LFQ); CST values are log₁₀-transformed. Pearson’s correlation coefficient (r) and p values (P) are given, with p < 0.05 being statistically significant.
