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: Metabolic dysfunction-associated steatotic liver disease (MASLD) and sarcopenia share underlying pathophysiological mechanisms and can bidirectionally influence the development and progression of each other. Diagnosing sarcopenia in individuals with MASLD is challenging due to overlapping symptoms and the frequent requirement for expensive, specialized equipment for muscle mass assessment. Therefore, accessible screening methods are crucial. Serum indices based on creatinine (Cr) and cystatin C (CysC), including Calculated Body Muscle Mass (CBMM), Sarcopenia Index (SI), and estimated glomerular filtration rate (eGFR) ratio, have emerged as potential biomarkers for sarcopenia. This study aimed to compare the performance of these serum indices in screening for low skeletal muscle index (SMI) among patients with MASLD. Methods: This prospective observational study enrolled 146 participants with MASLD. Anthropometric and laboratory data were collected. The CBMM, SI, and eGFR ratios were calculated using serum Cr and CysC levels. Low SMI was determined using Bioelectrical Impedance Analysis (BIA) according to the Asian Working Group for Sarcopenia (AWGS) 2019 criteria. Linear regression analysis was used to assess the correlations between serum indices and SMI. Receiver Operating Characteristic (ROC) curve analysis was used to evaluate the discriminative ability of these serum indices for detecting low SMI. Furthermore, machine learning models (Linear Regression, Random Forest, and XGBoost), coupled with SHapley Additive exPlanations (SHAP) analysis, were employed to evaluate the importance of these indices in predicting low SMI. Results: Patients with higher fibrosis-4 (FIB-4) scores (≥2.67) had a significantly higher prevalence of low SMI. CBMM demonstrated the strongest correlation with SMI (R Conclusion: These findings suggest that CBMM, derived from readily available serum markers, could serve as a valuable initial screening tool for identifying MASLD patients at risk of sarcopenia who may benefit from further assessment and early interventions.
