Risk factors and predictive model for mild cognitive impairment in elderly patients with rheumatoid arthritis.
Article in BMC rheumatology, 2025. 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
backgroundRheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by joint destruction and systemic inflammation, both of which significantly impair patients' quality of life. Mild cognitive impairment (MCI), a reversible precursor to dementia, is increasingly prevalent among elderly RA patients. Early identification of MCI in this population allows for timely interventions to slow cognitive decline.
objectiveThis study aims to identify independent risk factors for MCI in elderly patients with RA and to develop a predictive nomogram.
methodsWe enrolled 378 elderly RA patients, aged 60 to 80 years, from Xi'an Fifth Hospital between December 2023 and December 2024. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), with scores ranging from 20 to 26 indicating MCI. We analyzed demographic, clinical, and laboratory data to identify risk factors through logistic regression and constructed a nomogram. The model's performance was evaluated using receiver operating characteristic (ROC) curves, calibration plots, and decision curve analysis (DCA).
resultsAmong the 378 patients, 94 (24.87%) were classified in the RA-MCI group. Multivariate analysis identified the course of disease (COD) (OR = 1.07, 95% CI: 1.03-1.10), elevated Disease Activity Score-28 (DAS28) (OR = 1.31, 95% CI: 1.13-1.53), high C-reactive protein (CRP) levels (OR = 1.01, 95% CI: 1.01-1.02), and osteoporosis (OP) (OR = 1.88, 95% CI: 1.14-3.13) as independent risk factors. The nomogram demonstrated moderate discrimination (AUC = 0.750, 95% CI: 0.696-0.805) and clinical utility.
conclusionThe COD, OP, DAS28, and CRP levels are key predictors of MCI in elderly RA patients. The proposed nomogram provides a practical tool for early risk stratification, facilitating targeted interventions to delay cognitive decline.
trial registrationThis study conformed to the principles outlined in the Declaration of Helsinki and received approval from the Medical Ethics Committee of Xi'an Fifth Hospital (Approval No.: [2023] Ethics Review 55). Additionally, the trial was registered with the Chinese Clinical Trial Registry (Registration No.: ChiCTR2300077337, Registration Date: 2023-11-01). Written informed consent was obtained from all individual participants included in the study.
