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: Drug-induced liver injury (DILI) has become a major cause of acute liver failure, and its incidence has been increasing steadily in recent years. This study aimed to compare the clinical and computed tomography (CT) imaging features of the variable biochemical damage and severity of DILI to establish a radiological model for predicting high-risk DILI based on CT image features. Methods: The eligible patients with DILI (January 2016 to March 2024) who underwent serum laboratory examination and contrast abdominal CT within 3 months of onset were retrospectively analyzed at Affiliated Xihu Hospital of Hangzhou Medical College (Institution I) and The Second Affiliated Hospital of Zhejiang Chinese Medical University (Institution II). The severity-associated CT features were determined via binomial logistic regression analysis, and the efficacy of the different models were compared. The odds ratios (ORs) and corresponding 95% confidence intervals (CIs) provided were not adjusted. Results: The injury types included hepatocellular (n=68, 45.64%), mixed (n=28, 18.79%), and cholestatic (n=53, 35.57%). The proportion of splenomegaly in patients with cholestatic injury (56.60%) was significantly higher than that in those with hepatocellular (35.71%) and mixed injury (22.06%) (P<0.001). Regarding severity, 127 (85.23%) patients had mild-to-moderate injury, and 22 (14.77%) had severe-to-fatal injury or required liver transplantation (LT). Injury severity was independently associated with quantitative liver-spleen contrast (Q-LSC) (OR =0.002; 95% CI: 0.00-0.13), and ascites (OR =70.83; 95% CI: 16.34-306.99). The prediction of the new model employing Q-LSC and ascites for high-risk DILI demonstrated excellent performance [area under the receiver operating characteristic (ROC) curve (AUC) =0.929; sensitivity=0.818; specificity =0.953]. Conclusions: Statistical differences are observed in the serum biomarkers of DILI according to varying biochemical damage and degree of severity. Q-LSC and ascites were associated with the severity of DILI, and a combined model incorporating Q-LSC and ascites can effectively predict high-risk DILI.
