Temporal incidence and impact of dementia in rheumatoid arthritis: a cohort study.
Article in EULAR rheumatology open, 2026. 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
Objectives: The objective of this study is to address conflicting evidence that chronic inflammation may increase the risk of dementia in patients with rheumatoid arthritis (RA). Methods: Retrospective population-based study using longitudinally linked administrative health data over a 30-year period for ever hospitalised patients with RA (n = 14,041, age 64 years, 67.2% female) and controls (n = 33,785, age 65 years, 65.6% female). Dementia was defined by the International Classification of Diseases codes for Alzheimer's disease (AD), vascular dementia, and nonspecific dementia subtypes. Dementia incidence rate (IR) and mortality rate (MR) per 1000 person-years and comorbidities are reported. Results: During 9.6 years of follow-up, 1463 (10.4%) of patients with RA and 3701 (11%) of controls were diagnosed with dementia at respective age of 83 vs 84 years ( Conclusions: There was no difference in temporal incidence and MRs for dementia between patients with RA and matched controls. These data suggest that there is minimal impact of RA on the frequency and outcome of dementia.
