Early urinary sodium vs B-type natriuretic peptide for predicting 30-day outcomes in acute decompensated heart failure: a prospective cohort study.
Observational study in Croatian medical journal, 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
aimTo compare the prognostic performance of early urinary sodium (UNa) and B-type natriuretic peptide (BNP) for predicting 30-day adverse outcomes in emergency department (ED) patients with acute decompensated heart failure (ADHF).
methodsThis prospective observational study was conducted in the ED of Dokuz Eylül University Hospital, Izmir, between January 2025 and July 2025. The study enrolled adults presenting with dyspnea, diagnosed with ADHF, and treated with intravenous loop diuretics. Baseline and 2-hour spot UNa and serum BNP levels were measured. The primary outcome was a composite of intensive care unit admission at the index visit, ED revisit due to ADHF within 30 days, or 30-day all-cause mortality. Patients were compared according to the presence or absence of the composite outcome. Logistic regression and receiver operating characteristic analyses were performed.
resultsA total of 117 patients were enrolled, and the composite outcome occurred in 41 (35.0%). Baseline BNP and UNa levels did not differ significantly between the groups. However, 2-hour UNa was significantly lower in patients with the composite outcome than in patients without it (88.0±29.1 vs 107.3±16.6 mmol/L, P<0.001), whereas 2-hour BNP was comparable between the groups. In multivariable analysis, 2-hour UNa remained independently associated with the composite outcome (adjusted odds ratio 0.963; 95% confidence interval 0.942-0.986; P=0.001), while 2-hour BNP did not. In receiver operating characteristic curve analysis, 2-hour UNa showed significant discriminative ability (area under the curve [AUC] 0.739), whereas 2-hour BNP did not (AUC 0.542). The AUC of 2-hour UNa was significantly greater than that of 2-hour BNP (P=0.003).
conclusionLower 2-hour UNa was independently associated with 30-day adverse outcomes in ED patients with ADHF and may provide early prognostic information on natriuretic response. These findings require validation in larger multicenter studies.
