Geriatric nutritional risk index and mortality risk in elderly patients with rheumatoid arthritis: evidence from NHANES (1999-2018).
Article in Clinical rheumatology, 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
backgroundRheumatoid arthritis (RA) could increase all-cause and cardiovascular mortality, particularly in elderly patients. Malnutrition is usually found in RA and contributes to poorer outcomes, with geriatric nutritional risk index (GNRI) serving as a dependable indicator to provide information on nutritional risk in elderly populations. We aim to elucidate connection between GNRI and survival outcomes in elderly RA patients.
methodsUsing NHANES database from 1999-2018, 1,473 RA patients ≥ 60 years old have been chosen. Participants were categorized into High-GNRI and Low-GNRI group with a threshold of 98. Mortal status was extracted from the Linked Mortality Files. Cox regression was utilized to further assess the relationship.
resultsHigher GNRI was significantly associated with lower all-cause (HR 0.563, 95% CI 0.423-0.751, p < 0.001) and cardiovascular mortality (HR 0.571, 95% CI 0.345-0.946, p = 0.030) in fully adjusted models, which was confirmed by Kaplan-Meier survival curves. Subgroup analyses further validated these associations across various demographic and clinical groups.
conclusionHigher GNRI is independently associated with a lower risk of all-cause and cardiovascular mortality in elderly RA patients, underscoring the importance of nutritional status in the survival of this population. Key Points • Higher GNRI was significantly associated with lower all-cause and cardiovascular mortality in elderly patients with rheumatoid arthritis. • Restricted cubic spline analysis revealed a linear association, with mortality risk decreasing as GNRI increased.
