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
Sarcopenia is associated with poor outcomes in patients with cirrhosis. While computed tomography (CT)-derived skeletal muscle index (SMI) is considered the gold standard for diagnosis in this setting, its use is limited due to cost, radiation exposure, and availability. Our aim was to evaluate whether simple, non-radiating, easy-to-use methods, including ultrasound (US), bioelectrical impedance analysis (BIA), and anthropometry, could accurately identify sarcopenia in this population. A total of 250 patients with cirrhosis who underwent an abdominal CT scan were enrolled prospectively in this single-center, cross-sectional study. Within 1 month, the patients underwent assessments including anthropometry, handgrip strength, BIA [including body protein index (BPI)], and US of the psoas and thigh. Sarcopenia was defined by CT-based SMI at L3 (<50 cm 2 /m 2 in men, <39 cm 2 /m 2 in women). Thigh and psoas muscle thickness (normalized by height 2 ) and BPI showed moderate to strong correlations with SMI (ρ=0.42-0.71). Multivariable models combining thigh or psoas US with BMI and calf circumference achieved AUROCs of 0.837 and 0.822, respectively. A model using BPI and BMI showed comparable accuracy (AUROC, 0.844). Interobserver agreement for US measurements was high (Lin's coefficients 0.66-0.93). Thigh stiffness (2D-SWE) and phase angle did not correlate with SMI. Non-radiating tools, such as US-based thigh and psoas measurements, BIA-derived BPI, and anthropometry, are accurate alternatives to CT for detecting sarcopenia in patients with cirrhosis. These tools are simple, safe, and reproducible, which supports their integration into routine clinical practice for sarcopenia screening and monitoring.
