Aim:
To evaluate the overall diagnostic value of anti-citrullinated fibrinogen (ACF) antibody in patients with rheumatoid arthritis (RA).
Methods:
Published studies were systematically retrieved from PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), Wan Fang, China Biology Medicine (CBM) disc, and Chinese VIP databases. QUADAS-2 tool was applied to evaluate the quality of eligible studies. Subgroup analysis and meta-regression were used to explore the sources of heterogeneity. Egger's test was used to evaluate for the presence of publication bias.
Results:
Seven studies were included in this meta-analysis. The pooled sensitivity, specificity, pooled positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of ACF were 0.61 (95% CI: 0.57-0.64), 0.93 (95% CI: 0.92-0.94), 9.33 (95% CI: 5.15-16.92), 0.39 (95% CI: 0.30-0.53) and 24.58 (95% CI: 11.47-52.64), respectively. The area under the curve was 0.8018. The results of subgroup analysis and meta-regression indicated that the factors we analyzed might not be the leading causes of heterogeneity. No significant publication bias was found.
Conclusion:
The ACF antibody had a moderate diagnostic accuracy on RA.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
