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
Objective: The aim of this study is to demonstrate the reliability of Quantitative Ultrasound (QUS) in assessing liver fat content in children, using magnetic resonance imaging proton density fat fraction (MRI-PDFF) values as a reference, and to determine threshold values for QUS in grading hepatosteatosis. Methods: The study group consisted of pediatric patients under 18 years of age without known liver disease who volunteered to participate. All patients underwent MRI-PDFF scanning, and QUS imaging was performed using the tissue attenuation imaging (TAI) ve tissue scatter distribution imaging (TSI) tools. The cut-off values for MRI-PDFF were set at ≥5%, ≥16.3%, and ≥21.7%, corresponding to mild, moderate, and severe steatosis, respectively. The diagnostic performance of TAI and TSI in detecting various degrees of hepatic steatosis was evaluated using the area under the ROC (AUROC) curves. Results: The frequencies of hepatosteatosis grading were as follows: S1: 19 (37%), S2: 5 (10%), S3: 22 (43%). The AUROCs for TAI and TSI tools in detecting QUS measurements (MRI PDFF ≥5%) were 0.95 [95% confidence interval (CI): 0.91-0.99] (p< 0.001) and 0.96 (95% CI: 0.93-0.99) (p<0.001), respectively. For distinguishing different degrees of steatosis, TAI showed values of 0.75, 0.86, and 0.96 dB/cm/MHz, corresponding to sensitivities of 88%, 88%, and 100%, respectively, while TSI showed values of 92.44, 96.64, and 99.45, with sensitivities of 90%, 92%, and 91.7%. The correlation test between QUS measurements [TAI, TSI, EzHRI (Hepato-Renal Index with Automated regions of interest Recommendation)] and MR-PDFF indicated a concordance in TAI and TSI values, but not with EzHR. Conclusions: The TAI and TSI tools can accurately measure liver fat content and can be used reliably in children for the assessment and grading of hepatosteatosis.
