Metabolic profile changes in patients with rheumatoid arthritis detected using mass spectrometry.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundRheumatoid arthritis (RA) presents as pain, swelling and leads to irreversible damage in joint, and adversely affects the quality of life of patients with RA. However, the etiology of RA is still unclear, and novel biomarkers are demanded for the early prediction and diagnosis of RA and dissecting disease mechanisms.
objectiveThis study aimed at profiling the disordered metabolic pathways in RA and selecting potential biomarkers to distinguish RA patients from healthy individuals, and systematically investigated the associations between metabolites and the risk of RA.
methodsA total of 533 participants, including 382 healthy individuals and 151 RA patients, were recruited to explore altered metabolic profiles through the analysis of dried blood spot samples by mass spectrometry. Multiple algorithms were applied to identify potential biomarkers. Dose-response relationships were investigated by binary logistic regression and restricted cubic spline (RCS) analysis.
resultsThere were different metabolic profiles between RA and healthy individuals. After systematic selection, a metabolic panel consisting of C20, C5, Leu, C14:1/C16, Arg/(Orn + Cit), and C2/C0 was used to differentiate the two groups. Ten-fold cross-validation and test set were employed to evaluate prediction models. The receiver operating characteristic analysis demonstrated an area under the curve of 0.920(95%CI: 0.851-0.990) in test set to distinguish the two groups. The strong correlations between the 6 metabolites and RA were observed in RCS regression model.
conclusionsThe selected biomarkers have the potential to improve the detection of RA, and may offer insights into the intervention strategies to susceptible at-risk populations of developing RA.
