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
objectivesThis study aimed to identify key hepatic genes involved in metabolic dysfunction-associated steatotic liver disease (MASLD) pathogenesis and determine whether sleeve gastrectomy (SG) attenuates cafeteria diet-induced hepatic steatosis in a rat model. SUBJECT AND
methodsThirty-two male Sprague-Dawley rats were divided into four groups: control (lean), diet-induced obesity (DIO)-obese control, DIO-sham, and DIO-SG. Hepatic expression profiling of MASLD-associated genes was performed using RT2 Profiler polymerase chain reaction arrays. Circulating adipokines (leptin and adiponectin) and hepatic triglyceride (TG) content were also quantified.
resultsSG significantly reversed obesity-induced upregulation of key lipogenic (Fasn, Srebf1, Dgat2), gluconeogenic (G6pc, Gck), and inflammatory (Nfkb1, Il1b) genes, while enhancing fatty acid oxidation and mitochondrial pathways (Cpt2, Ppargc1a, Acadl). Pathway analysis demonstrated significant modulation of peroxisome proliferator-activated receptor and adenosine monophosphate-activated protein kinase signaling, fatty acid oxidation, and insulin sensitivity networks. Circulating leptin and hepatic TG content were significantly reduced following SG, consistent with systemic metabolic improvement. The normalization of Srebf1 and Dgat2 highlights restoration of hepatic lipid homeostasis and improved insulin sensitivity.
conclusionSG reduced hepatic fat accumulation and mitigated MASLD through broad transcriptional and metabolic reprogramming of lipid, oxidative, and inflammatory pathways. The identification of shared hepatic-whole-blood signatures together with improvements in circulating biomarkers underscores the systemic impact of SG and suggests potential translational targets for noninvasive monitoring and therapeutic intervention.
