This study aims to investigate the association between D-dimer and the risk of mortality in coronavirus disease 2019 (COVID-19) patients using a meta-analysis. We found that the D-dimer levels in non-survival patients were significantly higher than those in survival patients (SMD = 0.91, 95% CI = 0.79 to 1.03). In conclusion, the elevated D-dimer levels were associated with an increased risk of mortality in COVID-19 patients.
D-dimer is associated with the risk of mortality in Coronavirus Disease 2019 patients.
