Objective The ongoing pandemic of COVID‐19 caused by the novel coronavirus Syndrome‐Coronavirus‐2 (SARS‐CoV‐2) is an emerging, rapidly evolving situation. Excluded typical manifestation of pneumonia and acute respiratory symptoms, COVID‐19 patients also have abnormal D‐dimer concentration in the serum, but the results are controversial. Method A meta‐analysis first aims to explored the connection between D‐dimer concentration and COVID‐19 patients. Results Our results found a significant relationship between D‐dimer and COVID‐19, with a pooled OR of 1.90 (95% CI: 1.32‐2.48; P < .001). The pooled data were calculated with the REM as a high heterogeneity within the studies. The sensitivity analysis results showed that the WMD ranged from 1.69 (95% CI: 1.15 to 2.23) to 2.06 (95% CI: 1.51 to 2.62) and there was no publication bias. Conclusions Our meta‐analysis showed that the severity of patients with COVID‐19 significance related to D‐dimer concentrations. Meanwhile, the severe COVID‐19 patients tend to have a higher concentration of D‐dimer when compared with non‐severe patients. Review criteria We used MASH word and searched the online database and followed the inclusion and exclusion standard. The detailed information can be found in the text. Message for the clinic Our meta‐analysis showed that the severity of patients with COVID‐19 significance related to D‐dimer concentrations. This may be helpful for the clinic COVID‐19 patients.
