Changes in Blood Coagulation in Patients with Severe Coronavirus Disease 2019 (COVID-19): a Meta-Analysis

Coronavirus disease 2019 (COVID-19) is widely spread and poses a critical threat to global health (Zhang et al). Prominent changes in coagulation function in severe patients of COVID-19 have been reported in a recent study (Han, et al 2020). Therefore, we conducted this quantitative meta-analysis to explore the difference in blood coagulation parameters between severe and mild cases of COVID-19.
