However, in COVID-19 patients, we observed lower plasma levels of D-dimers, vWF-A2, sICAM1, sTREM1, VEGF, and sP-selectin as compared to non-COVID-19 patients, and a non-significant difference for plasma levels of sTM, TFPI, uPA, CXCL4, PDGF-AA and PDGF-AB/BB (Figure 1, Supplementary Table 2). The gene discussed is PF4; the disease is COVID-19.
