Impact of routine urine sodium evaluation on diuretic practices in patients with acute heart failure.
Article in ESC heart failure, 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
introductionNatriuresis-guided diuresis has been investigated in prospective trials for acute heart failure (HF), but its impact on diuretic prescribing in clinical practice is uncertain.
methodsFrom September 2021, routine urine sodium measurement was implemented for all patients admitted with acute HF to our intensive cardiac care unit. We compared diuretic prescribing in 160 prospective post-implementation patients (up to April 2023) with 206 historical controls (from January 2020). Multivariable logistic regression evaluated the odds of aggressive diuretic use, defined as the upper tertile of total furosemide dose administered within the first 72 h (≥340 mg). Propensity score matching on prespecified covariates created a balanced cohort for sensitivity analysis.
resultsThe median age was 71 (interquartile range 60-80), with 252 (69%) men. Post-implementation, patients received higher median total furosemide dose at 72 h (340 [180-525] mg vs. 220 [120-320] mg; P < .001), and were more likely to receive aggressive diuresis (adjusted OR 4.8, 95% CI 2.86-8.25; P < .001). Propensity score matching of 264 patients yielded consistent results (adjusted OR 5.2, 95% CI 3.004-9.46; P < .001). At 72 h, the post-implementation group had higher cumulative urine output (6250 mL vs. 4873 mL; P < .001) and more frequent resolution of jugular venous distension (25% vs. 5%; P < .001) and peripheral oedema (14% vs. 5%; P = .009), with no difference in pleural effusion (7% vs. 5%; P = .550).
conclusionRoutine urine sodium measurement in acute HF patients in intensive care settings was associated with more aggressive diuretic use, increased diuresis, and more rapid improvement in congestion markers.
