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: Liver cirrhosis, characterized by chronic inflammation, is frequently complicated by malnutrition. Nutritional indices, such as the prognostic nutritional index (PNI) and the skeletal muscle index (SMI), calculated as the muscle area quantified via CT scans at the third lumbar vertebra level divided by the square of the patient's height in meters (cm Objectives: We aimed to evaluate the diagnostic efficacy of the PNI both independently and in combination with the SMI for identifying malnutrition in cirrhosis and to explore their prognostic implications. Design: A single-center retrospective cohort study of 262 hospitalized cirrhotic patients (2018-2023). Malnutrition was assessed using PNI, PNI-SMI, and Global Leadership Initiative on Malnutrition (GLIM) criteria, respectively. Methods: Nutritional status was defined by PNI (<28.85), PNI-SMI (either reduced PNI or SMI), and GLIM criteria. SMI was quantified via third lumbar vertebra CT scans. Diagnostic performance was evaluated using sensitivity, specificity, and area under the curve (AUC). Cox regression and Kaplan-Meier analyses assessed associations with 1-year mortality. Results: The prevalence of malnutrition, as determined by various criteria, was considerably heterogeneous: 26.72% by the PNI, 56.11% by the PNI-SMI, and 51.14% by the GLIM criteria. Patients classified as malnourished demonstrated inferior clinical parameters and a higher 1-year mortality rate. The PNI-SMI combination exhibited favorable diagnostic performance in detecting malnutrition, with a sensitivity of 75.51%, specificity of 80%, along with an area under the curve of 0.774. Multivariate Cox analysis indicated that all three malnutrition criteria were independently associated with 1-year all-cause mortality, with hazard ratios of 2.56, 4.20, and 7.20, respectively. Conclusion: The PNI, particularly when integrated with the SMI, offers a streamlined yet moderately accurate tool for nutritional and prognostic assessment in decompensated cirrhosis. This combined approach may serve as a practical supplement to GLIM criteria in select clinical contexts, potentially improving outcomes through targeted nutritional interventions.
