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
backgroundBurn injury (BI) represents a major epidemiologic problem worldwide, mostly in children. BIs greater than 40% of the total body surface, are considered severe, and entail a hepatic hypermetabolic response, which is associated with proteins depletions and prolonged hypermetabolism.
objectiveThis study aims to evaluated the effects of short- and long-term insulin treatment on liver morphology and the use of a biomarker related to oxidative damage to DNA (8-OHdG) to better understand the anabolic action of this hormone in the liver.
methodsWistar rats aged 21 d were distributed into four groups: control (C), control with insulin (C+I), scald burn injury (SBI), and SBI with insulin (SBI+I). The SBI groups were subjected to a burn 45% total body surface area. The C+I and SBI+I groups received insulin (5 UI/Kg/d) for 4- or 14 d. The livers were analyzed for morphometric, histopathological, and immunohistochemical for 8-OHdG.
resultsThe main results showed that, in a short time, insulin increases the density of binucleated hepatocytes as an organ response to burn injury. In the long term, insulin increased the area of hepatocytes in the SBI+I group in relation to SBI, highlighting the similar values between the SBI+I and the control groups. Regarding sinusoidal cells, insulin was able to modulate this liver proliferative reaction. Insulin reduces 8-OHdG immunoexpression in short and long-term post-burn moments.
conclusionThe insulin modulation of 8-OHdG makes us infer that a study about the control of 8-OHdG as a potential biomarker in patients could be an efficient precursor of the level of oxidative stress associated with hepatic dysfunction associated to extensive burn injury.
