Figure 4

Correlation of S1P with S100A4 in the serum of COPD patients and control subjects. The correlation of S1P with S100A4 was determined through Pearson’s analysis between COPD patients and control subjects. (a) The correlation of S1P with S100A4 in all subjects. (b) The correlation of S1P with S100A4 in COPD patients. (c) The correlation of S1P with S100A4 in control subjects.
