Figure 4. Plasma ELISA of three protein biomarkers in cardiac transplantation.

Figure 4

We measured the protein concentrations of PECAM1 (A), CXCL9 (B) and CD44 (C) by ELISA in the plasma of 32 AR patients and 31 STA patients after cardiac transplantation. All three proteins have statistically significantly higher concentration in the AR serum samples, compared to STA as shown in the notched box plots. P-values were calculated using the Mann-Whitney U test. (D) In ROC curves used to distinguish AR from STA, the areas under the curves were 0.716, 0.672, and 0.711 for PECAM1, CXCL, and CD44, respectively.
