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 and aims: Cirrhosis is a major cause of morbidity, frequently leading to complications like hepatorenal syndrome (HRS). Diagnosing HRS is difficult, as serum creatinine (SCr), commonly used to assess renal dysfunction, has significant limitations in cirrhosis. This study explored renal resistive index (RRI) as a potential alternative for early detection of HRS.This study aimed to evaluate the utility of RRI as an early predictor of HRS in cirrhotic adults admitted to a tertiary intensive care unit (ICU). Patients and methods: A prospective observational study was conducted on 78 cirrhotic adult ICU patients. Renal resistive index was measured within 24 hours of admission. Clinical, biochemical, and ultrasound parameters were collected. Statistical analyses included analysis of variance (ANOVA), Results: Of 78 patients, 88.5% were male and 78.2% had alcohol-related cirrhosis. Hepatorenal syndrome occurred in 30.8% of cases. Renal resistive index showed a strong correlation with ascites grade, MELD-Na, and Child-Pugh class. Receiver operating characteristic analysis revealed RRI >0.705 had 87.5% sensitivity and 87.0% specificity in predicting HRS. The RRI elevation preceded the SCr rise by 24-48 hours. Backward stepwise conditional logistic regression, however, identified ascitic grade as the independent predictor of HRS ( Conclusion: Although ascitic grade was the sole independent predictor of HRS in our multivariate model, RRI was strongly associated with HRS onset and may offer additional utility alongside clinical parameters for early identification of at-risk patients.
