Prognostic Value of Urine Sodium in Patients With Acute Decompensated Heart Failure: A Systematic Review and Meta-Analysis.
Review in Cureus, 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
Acute decompensated heart failure (ADHF) remains a leading cause of hospitalization worldwide. The prognostic value of spot urinary sodium concentration in determining clinical outcomes for patients with ADHF treated with diuretics remains uncertain. This systematic review with meta-analysis was registered in the International Prospective Register of Systematic Reviews (CRD42024626912). MEDLINE, Cochrane, and Embase were searched from inception to May 2026 for studies comparing high and low urine sodium, measured after the first void or within six hours of diuretic use, in adult patients admitted for ADHF. The primary outcomes of interest were mortality, length of hospitalization/stay (LOS), inotrope use, and worsening renal function. Odds ratios (ORs) with 95% confidence intervals (CI) were pooled with a random-effects model. Quality assessment and risk of bias were performed according to Cochrane recommendations. A total of eight studies comprising 1,359 patients were included in the meta-analysis, of which 923 (67.9%) were categorized in the high urinary sodium group and 464 (32.1%) in the low urinary sodium group. In patients with ADHF, high urine sodium was associated with lower mortality (OR, 0.28; 95% CI, 0.12-0.68), reduced inotrope use (OR, 0.40; 95% CI, 0.25-0.62), lower worsening renal function (OR, 0.53; 95% CI, 0.32-0.86), and shorter LOS (mean difference, -4.35; 95% CI, -7.88 to -0.81) compared with low urine sodium. In patients with ADHF treated with diuretics, high urine sodium is associated with improved outcomes, including reduced mortality, inotrope use, worsening renal function, and shorter LOS, compared with patients with low urine sodium.
