Impact of anti-citrullinated protein antibody on tumor necrosis factor inhibitor or abatacept response in patients with rheumatoid arthritis.
Article in European journal of rheumatology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveTo assess the impact of anti-citrullinated protein antibody (ACPA) serostatus on response to treatment with either tumor necrosis factor inhibitors (TNFi) or abatacept in patients with rheumatoid arthritis (RA).
methodsData was obtained from the Optimizing Patient outcomes in Australian RheumatoLogy (OPAL) dataset. Patient data were included in the analysis if they commenced treatment with abatacept or TNFi between 01 August 2006 and 30 June 2017 and had at least 12 months' follow-up. The primary outcome was the mean change in the clinical disease activity index (CDAI) score from baseline to 12 months.
resultsA total of 2,052 patients were included of which 1,415 were in the TNFi cohort (n=1,053 ACPA positive) and 637 in the abatacept cohort (n=445 ACPA positive). Patients were predominantly female (75% TNFi; 80% abatacept) with no significant difference in age between cohorts. Patients with ACPA positivity had longer disease duration before commencing treatment in both the TNFi and abatacept cohorts compared to ACPA negative patients. No difference in disease severity was observed in those with ACPA negativity compared to those with ACPA positivity. Patients treated with TNFi and abatacept had significantly improved mean change in CDAI after 12 months; ACPA positivity was associated with greater response to treatment with abatacept compared to that in patients with ACPA negativity (p=0.011). No difference in response was observed based on ACPA serostatus in patients treated with TNFi (p=0.73).
conclusionBaseline ACPA positivity was associated with improved clinical response using CDAI outcome measure at 12 months for abatacept but not for TNFi therapies.
