Figure 5. Analysis of ANG-1 and ANG-2 concentrations in serum from CSDH patients, serum from healthy controls, or hematoma supernatants. (A) No differences in the serum ANG-1 concentration were observed between CSDH patients and healthy controls. The ANG-1 concentration was lower in hematoma supernatants compared to the concentration in serum. (B) No differences in the ANG-2 concentration were observed in serum from CSDH patients and healthy controls. The ANG-1 concentration was higher in hematoma supernatants compared to in serum. Data are presented as the mean ± SEM. **** p < 0.0001, #### p < 0.0001.
