Our study revealed that several indicators were related to the severity of the disease, including platelet associated parameters (PLT, PCT, PDW, MPV, P-LCR), cytokine (IL-6), coagulopathy parameters (PT, PTA, INR, d-dimer, FDP), and thrombosis-related indicators (IP-10, MCP-1). This evidence concerns the gene CCL2 and deep vein thrombosis.
