Metabolomic profiles underlying gout flares: a prospective study of people with gout.
Article in RMD open, 2025. 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
objectivesTo identify specific metabolomic profiles associated with gout flares in people with gout.
methodsParticipants with gout were sequentially enrolled. In cross-sectional analysis, data were analysed according to the presence of gout flare (acute group) or absence of gout flare (intercritical group) at the time of enrolment. Participants in the intercritical group were prospectively followed and analysed according to the development of gout flares (recurrent flare group) or no gout flare (no flare group) over 1 year. Relative abundances of metabolites in serum obtained at the baseline visit were measured by untargeted liquid chromatography-mass spectrometry. Risk of incident flare was analysed using least absolute shrinkage and selection operator (LASSO)-Cox regression and time-receiver operating characteristic (ROC). Machine learning models were performed to identify biomarkers in cross-sectional and longitudinal analysis, which was further optimised using quantitative targeted metabolomics in an independent validation cohort.
resultsParticipants in the acute and intercritical groups showed distinct metabolic profiles, including carbohydrate, lipid and nucleotide metabolism. Many metabolites were associated with recurrent gout flare in the prospective analysis. The metabolic risk score with six LASSO-derived metabolites, including 5-methoxytryptamine, differentiated well for gout flare risk, yielding an area under the ROC curve (AUC) of 0.82 (95% CI 0.74 to 0.90). Machine learning models achieved an AUC of 0.828 for comparison between the acute and intercritical groups. For the prediction of recurrent flare, AUC reached 0.807-0.867 with combined metabolites and clinical measurements.
conclusionsMetabolic reprogramming differentiates between the acute and intercritical stages of gout, and implicated metabolites may serve as biomarkers for future gout flares.
