Outcomes of Hospitalized Liver Cirrhosis Patients With COVID-19 Infection: A Retrospective Analysis.
Article in Cureus, 2025. 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
Background Patients with liver cirrhosis (LC) are at an increased risk of adverse outcomes associated with coronavirus disease 2019 (COVID-19). Existing studies have demonstrated a higher prevalence of malnutrition among COVID-19 patients. However, there is limited research assessing the impact of malnutrition on COVID-19 patients hospitalized with cirrhosis. Methodology We conducted a retrospective analysis of patients with LC admitted to hospitals in the United States in 2020 using the National Inpatient Sample (NIS) database. We compared in-hospital mortality, the risk for acute kidney injury (AKI), and length of stay (LOS) between malnourished and non-malnourished LC patients with COVID-19. Multivariable logistic regression analysis assessed the independent association between malnutrition in these patients and the outcomes of interest. Results Among 5,192 LC patients with COVID-19 and LC identified in the NIS database, 4,593 (88.5%) were not malnourished, and 599 (11.5%) were malnourished. The median age of non-malnourished patients was 63 (interquartile range (IQR) = 54-72) years, and that of malnourished patients was 64 (IQR = 56-72) years. Examining the baseline characteristics, the following did not have statistically significant differences: sex (male: non-malnourished: 60.4% vs. malnourished: 61.6%) and race (White: 50.5% vs. 49.9%). Malnourished patients with LC and COVID-19 were more likely to have hyponatremia (217; 36.2% vs. 1,200; 26.1%) and chronic kidney disease (CKD) (146; 24.4% vs. 928; 20.2%) but less likely to have hypertension (149; 24.9% vs. 1484; 32.3%), hyperlipidemia (141; 23.5% vs. 1441; 31.3%), obesity (75; 12.5% vs. 1010; 22.0%), and diabetes (53; 8.8% vs. 718; 15.6%). Malnourished patients had a significantly higher in-hospital mortality rate (171; 28.5%) compared to non-malnourished patients (836; 18.2%) (p < 0.001). Malnutrition in LC and COVID-19 patients was associated with an increased risk of in-hospital mortality (adjusted odds ratio (aOR) = 1.36, 95% confidence interval (CI) = 1.09-1.69, p < 0.01), AKI (aOR = 1.78, 95% CI = 1.47-2.16, p < 0.01), and LOS (unstandardized coefficient = 5.29, 95% CI = 4.52-6.06, p < 0.01). Conclusions Malnutrition in hospitalized LC patients with COVID-19 was associated with a higher risk of in-hospital mortality, AKI, and LOS. These findings highlight the importance of multidisciplinary management in addressing the nutritional status of COVID-19 patients with LC.
