What is rheumatoid factor? From screening to personalized management.
Review in Rheumatology (Oxford, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The RF is a representative autoantibody against the crystallizable fragment (Fc) of denatured IgG that is primarily detected in patients with RA. Although five types of TNF inhibitors can be used to treat RA, no guidelines are available for selecting the appropriate inhibitor for treatment. High serum RF levels are associated with high disease activity, progressive joint destruction, life prognosis associated with organ damage, decreased treatment responsiveness to TNF inhibitors and other drugs and low treatment retention rates. Meanwhile, certolizumab pegol (CZP), a TNF inhibitor without the Fc region, remains at high concentrations in the blood. Unlike other antibody drugs with the Fc region, CZP maintains efficacy in patients with high serum RF levels. When serum IgM-RF levels are high, antibody drugs with the Fc region are more likely to bind to IgM-RF and be degraded. Thus, CZP without the Fc region may be more favourable for patients with high serum RF levels.
