Diagnostic performance of a new vimentin-derived ACPA (CCP high sensitive) in patients with rheumatoid arthritis.
Article in Immunologic research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Autoantibodies are a common feature of rheumatoid arthritis (RA), and their detection is used as a diagnostic tool in medical practice. Rheumatoid factor (RF) and/or anti-citrullinated protein antibodies (ACPA) detection in patients' sera are now included in 2010 ACR/EULAR criteria for RA diagnosis. In this study, we evaluated a new vimentin-derived ACPA ELISA, the anti-cyclic citrullinated peptide high sensitive (CCP hs) test, and we compared its performance with the RF IgM and anti-CCP3 tests on a French multicenter cohort of 84 RA patients, 107 non-RA patients and 100 healthy controls. Sensitivities for RA diagnosis were 71.4, 84.5 and 64.3 % and specificities were 88.4, 86.9 and 87.3 % for CCP hs, CCP3 and RF IgM, respectively. There was a moderate correlation between CCP hs and CCP3 titers (Pearson's r = 0.43; p < 0.0001). These results support the contention that anti-CCP hs antibodies are new reliable ACPA with high specificity for RA.
