Markers of Hepatic Insulin Clearance and Their Association With Steatosis in Hyperinsulinaemic Horses.
Article in Journal of veterinary internal medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundHyperinsulinaemia (HI) is an important feature of Equine Metabolic Syndrome (EMS). It has been suggested that reduced hepatic clearance of insulin contributes to HI, particularly in humans affected by metabolic dysfunction-associated steatotic liver disease (MASLD). HYPOTHESIS: In obese horses with HI, insulin clearance is impaired and associated with MASLD. ANIMALS: Tissue samples were collected at post-mortem from clinically well-characterized horses with HI (n = 13; basal insulin > 20 mIU/l) and without HI (control; n = 20).
methodsRetrospective observational study. Molecular drivers of hepatic clearance (CAECAM-1, an insulin chaperone protein and IDE-Insulin Degrading Enzyme) were quantified by RT-qPCR and activity, respectively, in liver tissue. Fixed liver sections stained with hematoxylin and eosin (H&E) were assigned a histological score by two blinded observers using an equine liver disease score and a human MASLD score. Triglyceride (TG) content in liver sections, serum liver enzymes, ACTH, basal insulin, and serum triglycerides were also measured.
resultsIDE activity was 2.73 (IQR 4.00 activity/mg of protein) in HI horses and 2.18 (IQR 0.55) in controls (p = 0.07). IDE activity correlated negatively with insulin (rho = 0.561, p = 0.04) but not with liver or serum TG. CEACAM-1 gene expression was higher in the HI group (2.09 ± 1.79 folds) than in controls (0.69 ± 0.62, p = 0.03). Liver disease and MASLD scores were no different between groups, whereas triglyceride liver content was higher in horses with HI (504.83 IQR 217.51 nmol/g) compared to controls (363.58 IQR 67.32 nmol/g, p = 0.04). CONCLUSIONS AND CLINICAL RELEVANCE: MASLD is not consistently present in HI horses, but CAECAM-1 expression is higher.
