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
backgroundObesity-induced inflammation mechanism is seen as a mechanism that may be the cause of insulin resistance and non-alcoholic fatty liver disease (NAFLD). Pathological destruction of insulin signaling molecules such as insulin receptor substrate proteins (IRS), especially due to the increase of cytokine signal suppressors (SOCS), has been demonstrated in experimental diabetes. The aim of this study was to determine the effects of metformin, pioglitazone, exenatide and exercise treatments used in type 2 diabetes on fatty liver and the role of Irs-1 and Socs3 molecules in this process in obese diabetic rats.
methodsThe study was conducted on 48 Wistar albino adult male rats weighing 180-220 g and randomly divided into 6 groups. The obese rat model with fatty liver was formed with a 60% fat diet for 4 weeks. Afterwards, drug treatment with metformin (Ob + D + M), pioglitazone (Ob + D + P), exenatide (Ob + D + ExA)) or exercise (Ob + D + ExE) was applied for 4 weeks to these obese groups, in which diabetes was induced by streptozocin (STZ). At the end of the experimental protocol, liver tissue samples were taken from all rat groups and histopathological and genetic analyses were performed.
resultsThe mean steatosis degrees of the Ob + D + ExA and Ob + D + ExE groups were statistically significantly decreased compared to the obese diabetic group (p < 0.001). The group with the lowest mean steatosis grade was the Ob + D + ExE. Decrease in SOCS-3 expression was significant in Ob + D + M and Ob + D + P groups than other groups (p < 0.05). Mean staining intensities of Ob + D + Ex group, Ob + D + ExE group and Ob + D + P group according to IRS-1 expression statistically significantly increased compared to obese diabetic group (p < 0.05). Average staining intensity of Ob + D + ExE group according to IRS-1 expression was significant than other groups.
conclusionExercise and exenatide treatments seemed to be the prominent treatment methods by showing a statistically significant effect in decreasing the degree of steatosis, decreasing the Socs3 expression level and increasing the Irs-1 expression level.
