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
introductionShear wave elastography (SWE) is widely used to assess liver stiffness in chronic liver disease. Increased stiffness may also occur in congestive liver disease (CLD) due to hepatic venous congestion in patients with cardiovascular disease, but data on its diagnostic performance remain limited.
objectivesTo evaluate the diagnostic performance of SWE for detecting CLD in outpatients with structural heart disease undergoing investigation for liver disease.
methodsConsecutive patients referred for SWE between 2018 and 2023 were retrospectively reviewed. CLD was defined by compatible liver imaging findings and structural heart disease on transthoracic echocardiography. Diagnostic performance was assessed using ROC analysis. Associations between liver stiffness and echocardiographic parameters were evaluated using correlation and partial correlation analyses, and determinants of liver stiffness were assessed using multiple linear regression.
resultsAbout 88 patients were included (17 with CLD). Liver stiffness was higher in CLD compared with non-CLD patients (8.4 [7.5-9.6] vs. 7.2 [6.5-8.2] kPa, p < 0.001). A cutoff > 7.54 kPa yielded an AUC of 0.757, with 81.2% sensitivity and 63.4% specificity. CLD was associated with right ventricular dilation and greater tricuspid regurgitation severity. Significant correlations were observed with right ventricular diameter, pulmonary artery systolic pressure, right atrial volume, and left atrial volume index. In multiple linear regression, CLD remained the only independent determinant of liver stiffness.
conclusionsSWE shows moderate diagnostic accuracy for detecting congestive hepatopathy in patients with structural heart disease. Liver stiffness appears to reflect systemic venous congestion rather than isolated hepatic structural disease.
