Association of albumin-bilirubin score with clinical severity and outcome in patients with decompensated heart failure: a retrospective cohort study.
Article in BMC cardiovascular disorders, 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
backgroundThe Albumin-Bilirubin (ALBI) score is a simple marker of hepatic function that may reflect systemic congestion in heart failure. Therefore, the present retrospective cohort study aimed to investigate the association between ALBI score and clinical severity, echocardiographic findings, and hospitalization outcomes in patients admitted with decompensated heart failure. Exploratory analyses were additionally performed to examine potential associations between ALBI score and in-hospital mortality.
methodsThis retrospective cohort study included adults (≥ 18 years) admitted with decompensated heart failure with reduced or mildly reduced ejection fraction at Rajaiee Hospital, Alborz University of Medical Sciences, Karaj, Iran, from March 2022 to March 2025. 152 patients met the inclusion criteria after excluding those with preserved ejection fraction, liver or renal disease, malignancy, or incomplete data. Clinical, laboratory, and echocardiographic data were extracted. The ALBI score was calculated using serum albumin and bilirubin. Statistical analysis included correlation, t-tests, multivariable linear regression, and ROC curve analysis.
resultsA total of 152 patients (47.4% female) with a mean age of 66.70 ± 12.73 years were included. Mean left ventricular ejection fraction (LVEF) was 27.34 ± 13.15%. Because only three in-hospital deaths occurred, mortality-related analyses were considered exploratory. In-hospital mortality occurred in 3 patients (2%), whereas other patients were discharged, with no significant difference in ALBI score between survivors and non-survivors (p = 0.709). Mean hospitalization duration was 7.85 ± 5.59 days. The mean ALBI score was - 2.79 ± 0.45 in females and - 2.64 ± 0.46 in males (p = 0.040). Patients with LVEF ≤ 30% had significantly higher ALBI scores than those with LVEF > 30% (- 2.65 ± 0.44 vs. - 2.83 ± 0.46, p = 0.022). However, no significant correlation was found between age and ALBI score (r = - 0.055, p = 0.499), but multivariable analysis showed that presenting comorbidity of hypertension (β = -0.187, p = 0.009) was independently associated with ALBI score. Analysis showed a small, significant association of AST (β = -0.006, p = 0.035) and ALP (β = 0.001, p = 0.030) with ALBI score as well. Through the analysis, ALBI showed weak predictive ability for prolonged hospitalization (AUC = 0.58, 95% CI: 0.49-0.68, p = 0.078).
conclusionThe ALBI score was associated with sex and heart failure severity, whereas analyses of in-hospital mortality remained exploratory because of the low number of events. Larger studies are needed to confirm its clinical utility.
