Our results showed that although plasma and serum VEGF tended to be higher in those who subsequently developed thrombosis than those who did not (mean difference 70.2 pg/mL for serum, and 11.44 pg/mL for plasma VEGF, 95% CI −2.39–25.73,p = 0.10), this was not found to be statistically significant. The gene discussed is VEGFA; the disease is Venous thrombosis.
