Leveraging dynamic serum uric acid trajectories for risk stratification in hospitalized HFpEF patients.

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
Background: Single-timepoint SUA measurement provides limited prognostic insight in acute heart failure with preserved ejection fraction (HFpEF). This study assessed whether dynamic in-hospital SUA trajectories (using admission and pre-discharge measurements) are more strongly associated with long-term outcomes than static single-timepoint measures. Methods: The cohort consisted of 4,164 acute HFpEF patients, drawn from the China Heart Failure Center Registry. The primary outcome was a major adverse cardiovascular events (MACE). SUA at admission and pre-discharge was analyzed as continuous using Cox regression. Patients were categorized to four dynamic trajectory groups according to admission and pre-discharge SUA (cut-off 7 mg/dL): persistently normal (N-N), escalating (N-H), de-escalating (H-N), and persistently elevated (H-H). The optimal prognostic SUA cut-off was determined by ROC analysis. Results: Over a median of 25.2 months, 900 patients (21.6%) experienced the primary outcome. Multivariable Cox regression showed that pre-discharge SUA (HR 1.23, 95% CI 1.18-1.29, Conclusion: In hospitalized HFpEF patients, dynamic SUA trajectories are more strongly associated with MACE than single measurements. Identifying high-risk patterns prior to discharge may inform risk stratification and generate the hypothesis that nutritional or other modulatory strategies targeting SUA trajectories could be tested in future prospective studies to determine whether they improve outcomes.
