Abstract Introduction There is good evidence that specific autoimmune rheumatic diseases (RDs), for example, rheumatoid arthritis and systemic lupus erythematosus (SLE), are associated with a state of hypercoagulability and an increased risk of venous thromboembolism (VTE). However, limited information regarding this association is available for other autoimmune or autoinflammatory RDs. We sought to address this issue by conducting a systematic review and meta‐analysis of the association between the d‐dimer, an established marker of hypercoagulability and VTE, and RDs and the possible clinical and demographic factors mediating this association. Methods We searched the electronic databases PubMed, Web of Science, and Scopus from inception to January 31, 2024. The risk of bias and the certainty of evidence were assessed using the Joanna Briggs Institute Critical Appraisal Checklist and GRADE, respectively. Results In 31 studies selected for analysis (2724 RD patients and 3437 healthy controls), RD patients had overall significantly higher d‐dimer concentrations when compared to controls (standard mean difference = 0.93, 95% CI 0.76−1.10, p |
