Figure 4: Demonstrates scatter blots with the correlation curves between VEGF-A and its receptors VEGFR-1 and VEGFR-2. Figure 4A shows the correlation between VEGF-A and VEGFR-1 with a correlation coefficient of 0.340 and a p-value of p=0.02. Figure 4B shows the correlation between VEGF-A and VEGFR-2 with a correlation coefficient of 0.278 (p=0.05). Figure 4C shows the correlation between VEGFR-1 and VEGFR-2 with a correlation coefficient of 0.480 (p<0.001).
