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
Purpose: To evaluate circulating liver-expressed antimicrobial peptide 2 (LEAP2) as a potential noninvasive biomarker for the presence of metabolic dysfunction-associated fatty liver disease (MAFLD) and its progression to metabolic dysfunction-associated steatohepatitis (MASH). Patients and Methods: This prospective observational study enrolled obese patients with MAFLD, categorized into simple steatosis (SS) or MASH based on liver histopathology, along with healthy controls (HC). Serum levels LEAP2 were quantified using enzyme-linked immunosorbent assay (ELISA). Baseline characteristics were compared among groups, followed by univariable and multivariate ordinary logistic regression to identify MAFLD predictors. The diagnostic performance of LEAP2 was evaluated through receiver operating characteristic (ROC) curve analysis. Additionally, Hepatic LEAP2 transcriptomic data from public Gene Expression Omnibus (GEO) datasets (GSE126848, GSE135251) were analyzed for validation. Results: Seventy-four participants (24 HC, 24 SS, 26 MASH) were analyzed. Serum LEAP2 levels significantly and progressively increased with MAFLD severity (median ng/mL: HC 11.54, SS 13.62, MASH 18.34; P<0.001), correlating positively with disease stage (Spearman's Conclusion: Serum LEAP2 levels progressively increase with MAFLD severity and are independently associated with the disease. LEAP2 demonstrates potential as a noninvasive biomarker for assessing MAFLD severity, particularly in distinguishing MASH from healthy individuals. These findings warrant further investigation into LEAP2's pathophysiological role and therapeutic potential.
