Compared to DVT- cancer patients, DVT+ showed an increased fold change of 1.28 (95% CI: 1.20–1.37; p<0.0001), 1.34 (95% CI: 1.23–1.46; p<0.0001), 1.41 (95% CI: 1.30–1.54; p<0.0001), and 1.61 (95% CI: 1.45–1.78; p<0.0001) for IL-6, TNF-α, Il-1β, and VEGF, respectively. This evidence concerns the gene IL6 and deep vein thrombosis.
